A选项：①不能是can tend！
②there's also the problem with "if [participle]" -- a modifier that, by convention, refers to the SUBJECT of the sentence (not the proximate noun).
for instance:
Animal 1 will attack animal 2 if injected with enough of the hormones related to aggression.
--> in this sentence it is animal 1, not animal 2, that is being injected with hormones.

D选项：主谓抽出来应为jay can remember and tends to
it tends not to bother recovering a perishable treat stored long enough to have rotted.它往往不会费心回收一种易腐烂的食品，这种食品储存的时间太长，以致腐烂。
stored long enough to have rotted作定语，修饰treat，指食品具有被存储太久以致腐烂的性质
