Task: Answer the multiple choice question.
Query: Which drug exhibits a 20.172\% 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: COc1ccc(S(=O)(=O)N2CCC(O)(c3ccc(Cl)cc3)CC2)cc1
b: CN(C)c1ccc(/C=N/NC(=O)CNC(=O)c2ccc3c(c2)OCCO3)cc1
c: CCN(CC)C(=O)CSc1nnc(-c2ccccc2)o1
d: Cc1snc(S(=O)(=O)Cc2c(Cl)cccc2Cl)c1C#N
Answer: a. COc1ccc(S(=O)(=O)N2CCC(O)(c3ccc(Cl)cc3)CC2)cc1
