Task: Answer the multiple choice question.
Query: Which compound exhibits a -2.132% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a CCOC(=O)N1CCN(C(=O)COc2ccc3c(c2)C(=O)CC2(CCN(C(C)=O)CC2)O3)CC1
b N#Cc1ccsc1NC(=O)C1=COCCO1
Answer: a. CCOC(=O)N1CCN(C(=O)COc2ccc3c(c2)C(=O)CC2(CCN(C(C)=O)CC2)O3)CC1
