Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.502\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CS(=O)(=O)N1N=C(c2ccc(Br)cc2)CC1c1cccs1
(b) O=C(/C=C/c1ccccc1[N+](=O)[O-])NCCc1ccc(F)cc1
(c) COc1ccc(N2CCN(CC(O)COCCOc3ccc(Br)cc3)CC2)cc1.Cl
(d) O=C(NNc1ccc(F)cc1F)C1CCC1
Answer: b. O=C(/C=C/c1ccccc1[N+](=O)[O-])NCCc1ccc(F)cc1
