Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.899\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCCc1nc(C)c(-c2ccc(OC)c(OC)c2)c(=O)[nH]1
[b] CC(=O)Nc1ccc(S(=O)(=O)N(C)CC(=O)N/N=C/c2ccc(C(=O)O)cc2)cc1
[c] CN(C)CCCNS(=O)(=O)c1cc(Cl)c(Cl)cc1Cl
Answer: a. CCCc1nc(C)c(-c2ccc(OC)c(OC)c2)c(=O)[nH]1
