Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 16.926\% human ether-à-go-go related gene (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 other words.
Options:
a) COc1ccc(CCNC(=O)c2n[nH]c(=O)c3ccccc23)cc1
b) O=C(Nc1ccccc1)c1ccc(=O)n(Cc2ccc(F)c(F)c2)c1
c) Cc1ccc(Nc2[nH]c(=O)c3ccccc3c2C(=O)c2ccccc2)cc1
d) Cc1ccc(NC(=O)COC(=O)c2cc(Cl)ccc2[N+](=O)[O-])cc1
Answer: a. COc1ccc(CCNC(=O)c2n[nH]c(=O)c3ccccc23)cc1
