Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.403\% 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) CCCn1cc(S(=O)(=O)c2ccc(C)cc2)c(=O)c2cc(OCC)ccc21
(b) CCNc1nc(NC(C)(C)C)nc(Oc2ccc(=O)n(-c3ccccc3)n2)n1
(c) O=C(CCCC1=NS(=O)(=O)c2ccccc2N1)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1
(d) COc1ccc(OC)c(NC(=O)Cn2cc(C#N)c3cc(Br)ccc32)c1
Answer: b. CCNc1nc(NC(C)(C)C)nc(Oc2ccc(=O)n(-c3ccccc3)n2)n1
