Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 16.244\% 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) O=C(O)CCSc1nc2ccccc2n1Cc1ccccc1
b) O=C(NCC1CCCCC1)c1cc([N+](=O)[O-])ccc1Cl
c) O=C(O)c1ccc(NC(=O)c2cccc(NC(=O)c3cccs3)c2)cc1
Answer: b. O=C(NCC1CCCCC1)c1cc([N+](=O)[O-])ccc1Cl
