Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.916\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) CCOc1ccc2[nH]c(S(=O)(=O)CC)nc2c1Cl
b.) CCCc1ccc(C(C)NC(=O)c2cnccn2)cc1
c.) COc1ccc(C)cc1NC(=O)C(C)N(c1ccc(C)cc1)S(C)(=O)=O
d.) Cn1ccc2c([N+](=O)[O-])cccc2c1=O
Answer: a. CCOc1ccc2[nH]c(S(=O)(=O)CC)nc2c1Cl
