求问句子成分

不装逼会死星人

请问红色字体在句子中做什么成分？个人觉得像是同位语从句，但好像怪怪的- -

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
E. tends not bothering to recover a perishable treat it

红色是插入语 起到解释 说明作用 解释的是前面的这个 jay can remember.....
