Did the payload mean one 2,000-pound bomb?

Does that payload mean two bombs or a single 2,000-pound bomb?

Probably a single 2,000-pound bomb for two of the displayed aircraft, with doubt about the third. The captions do not establish which aircraft each visual reference indicates.

The question distinguishes total bomb load from the ability to carry a single heavy weapon. Two of the aircraft shown are tentatively identified as capable of taking one 2,000-pound bomb, while the third is doubted. The captions do not make those visual references clear enough to assign each answer to an aircraft model.
