a. The Tow boat and barge because they are "Not Under command"
b. The Tow boat and barge because they are "Restricted in their ability to maneuver"
c. The Sailboat
d. Who every blasted their maneuvering signal first.
Try to answer it yourself.
Remember it is a trick question.

Ha, indeed the question proposed by
Captain Graham is "tricky" in that it is based on a false premise. With the sailboat [that is sailing and NOT motoring]
there is not a "crossing situation" as specified in Rule 15.
Instead there is a
Keep Out of the Way situation.
—INTERNATIONAL—
Steering and Sailing Rules
RULE 18
Responsibilities Between Vessels
Except where Rules 9, 10 and 13 otherwise require:
(a) A power-driven vessel underway shall keep out of the way of:
(i) a vessel not under command;
(ii) a vessel restricted in her ability to maneuver;
(iii) a vessel engaged in
fishing;
(iv) a sailing vessel.
(b) A sailing vessel underway shall keep out of the way of:
(i) a vessel not under command;
(ii) a vessel restricted in her ability to maneuver;
(iii) a vessel engaged in fishing.
(c) A vessel engaged in fishing when underway shall, so far as possible,
keep out of the way of:
(i) a vessel not under command;
(ii) a vessel restricted in her ability to maneuver.
(d)
(i) Any vessel other than a vessel not under command or a vessel
restricted in her ability to maneuver shall, if the circumstances of the
case admit, avoid impeding the safe
passage of a vessel constrained
by her
draft, exhibiting the signals in Rule 28.
(ii) A vessel constrained by her
draft shall navigate with particular
caution having full regard to her special condition.
And since there is a Keep Out of the Way situation then there are the according Actions to be taken rules 16 and 17. But it all starts with who is to Keep Out of the Way of the other.
RULE 16
Action by Give-way Vessel
Every vessel which is directed to keep out of the way of another vessel
shall, so far as possible, take early and substantial action to keep well clear.
RULE 17
Action by Stand-on Vessel
(a)
(i) Where one of two vessels is to keep out of the way the other shall
keep her course and speed.
(ii) The latter vessel may however take action to avoid
collision by her
maneuver alone, as soon as it becomes apparent to her that the vessel
required to keep out of the way is not taking appropriate action in
compliance with these Rules.
(b) When, from any cause, the vessel required to keep her course and
speed finds herself so close that
collision cannot be avoided by the action of
the give-way vessel alone, she shall take such action as will best aid to
avoid collision.
(c) A power-driven vessel which takes action in a crossing situation in
accordance with subparagraph (a)(ii) of this Rule to avoid collision with
another power-driven vessel shall, if the circumstances of the case admit,
not alter course to port for a vessel on her own port side.
(d) This Rule does not relieve the give-way vessel of her obligation to keep
out of the way.
Okay lets take the question to another level of "trickery", let us make the assumption that the sailboat is sailing, and the tow boat and barge are also sailing.
