求大牛指教一个sc问题，逗号和and能连接共用主语的两个动词吗

GWD的一道题，因为看了曼哈顿，逗号和and不能连接共用主语的两个动词，所以首先就把A,D,E排除了

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 to recover a perishable treat it

D. tends not to bother recovering a perishable treat      (D)

E. tends not bothering to recover a perishable treat it

这是曼哈顿的例句：
Wrong: Earl walked to school, AND later ate his lunch

Right: Earl walked to school AND later ate his lunch

Right: Earl walked to school, AND HE later ate his lunch.

可是，这题为什么选D呢？我在网上找了很久，没找到有人回答到这一点，那以后再看到这样的题，还按照曼哈顿的说法做吗？

求大牛指教，快崩溃了~
