Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.123\% 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 other words.
Options:
(a) O=C(c1ccccn1)N1CCCC(N2CCN(c3cccc(C(F)(F)F)c3)CC2)C1
(b) COc1ccc(OC)c(S(=O)(=O)Nc2cc(OC)c(Cl)cc2OC)c1
(c) CCOC(=O)c1c(C)n(Cc2ccccc2)c2ccc(OCC(O)CNC(C)(C)C)cc12
(d) CCN1CCN(Cc2ccc(NC(=O)c3ccc(C)c(NC(=O)c4cccc5[nH]ccc45)c3)cc2C(F)(F)F)CC1
Answer: b. COc1ccc(OC)c(S(=O)(=O)Nc2cc(OC)c(Cl)cc2OC)c1
