Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 1.686\% 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 other words.
Options:
(a) CCc1cccc(NC(=O)Cn2cc3c(n2)CCCC3)c1
(b) O=C(O)C1C2C=CC(C2)C1C(=O)N1CCOCC1
(c) Cc1[nH]n(-c2ccccc2)c(=O)c1C(=O)c1ccc([N+](=O)[O-])cc1
(d) Cc1c(NC(=O)CSc2nnc(-c3ccco3)n2-c2ccccc2)c(=O)n(-c2ccccc2)n1C
Answer: b. O=C(O)C1C2C=CC(C2)C1C(=O)N1CCOCC1
