Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.490\% 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, or c without using any additional words.
Options:
(a) CCOC(=O)c1cc(-c2cccs2)nn1CCC#N
(b) O=C(NNS(=O)(=O)c1ccccc1[N+](=O)[O-])c1ccncc1
(c) CN(C)S(=O)(=O)N(CC(=O)N1CCN(c2ccccc2F)CC1)c1ccccc1
Answer: b. O=C(NNS(=O)(=O)c1ccccc1[N+](=O)[O-])c1ccncc1
