Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 3.949\% 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, or c without using any other words.
Options:
(a) O=S(=O)(Nc1ccc2c(c1)nc1n2CCN(Cc2ccccc2)C1)c1ccc(Cl)cc1
(b) O=C(O)c1cc(=O)[nH]c2c(Cl)cccc12
(c) C=CCNc1nc(C)c(CNc2c(C)cc(C)cc2C)nc1C#N
Answer: b. O=C(O)c1cc(=O)[nH]c2c(Cl)cccc12
