Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.006\% 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 additional words.
Options:
(a) CCCC(C)C(=O)Nc1ccc(C(N)=O)cc1
(b) COc1ccc(S(=O)(=O)N2CCSC2c2ccccc2)cc1
(c) O=C(CCc1ccc(Oc2cc([N+](=O)[O-])cc([N+](=O)[O-])c2)cc1)N1CCCCCC1
Answer: b. COc1ccc(S(=O)(=O)N2CCSC2c2ccccc2)cc1
