A scrub jay can remember when it cached a particular piece of food in a particular place, researchers have discovered, and tend not to bother to recover a perishable treat if stored long enough to have rotted.

 

A.      tend not to bother to recover a perishable treat if

B.       they tend not to bother recovering a perishable treat

C.      tending not to bother recovering a perishable treat if

D.      tends not to bother recovering a perishable treat

E.       tends not bothering to recover a perishable treat if
