Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 14.281\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(COc1ccc([N+](=O)[O-])cc1)NNC(=O)c1cccnc1
b: CCC(C)(C(=O)NC1CCCC1)N(C(=O)Cc1cccs1)c1c(C)n(C)n(-c2ccccc2)c1=O
c: Cc1nc(=O)c(-c2ccccc2)c(C)n1-c1cccc(C(=O)O)c1
Answer: a. O=C(COc1ccc([N+](=O)[O-])cc1)NNC(=O)c1cccnc1
