Task: Answer the multiple-choice question.
Question: Which drug has a 4.873\% 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 additional words.
Options:
(a) O=C(COc1cccc(NC(=O)c2cccc([N+](=O)[O-])c2)c1)c1ccc(Br)cc1
(b) O=C(/C=C/c1ccco1)Nc1cccc(NC(=O)/C=C/c2ccco2)n1
(c) Cn1c(=O)[nH]c(=O)c2c1nc(CN1CCN(Cc3ccccc3)CC1)n2CC(N)=O
(d) O=C(O)C1CC(c2ccc(F)cc2)=NO1
Answer: b. O=C(/C=C/c1ccco1)Nc1cccc(NC(=O)/C=C/c2ccco2)n1
