Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.392\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCN(Cc1cccs1)C(=O)CN1C(=O)NC2(CCCc3ccccc32)C1=O
b) CCOC(=O)c1ccc(-n2ccnc2)c(NC(=O)c2ccc(C(C)(C)C)cc2)c1
c) O=C(c1ccccc1)N1CCN(C(=O)c2cc3nc(-c4ccccc4)cc(C(F)(F)F)n3n2)CC1
Answer: a. CCN(Cc1cccs1)C(=O)CN1C(=O)NC2(CCCc3ccccc32)C1=O
