Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 3.981\% 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 S=c1nc(-c2csc3c2CCCC3)[nH][nH]1
b CN(C)C(CNC(=O)CCCc1c[nH]c2ccccc12)c1ccco1
c CC1CCN(C2=C(NS(=O)(=O)c3ccc(Cl)cc3)C(=O)c3ccccc3C2=O)CC1
Answer: c. CC1CCN(C2=C(NS(=O)(=O)c3ccc(Cl)cc3)C(=O)c3ccccc3C2=O)CC1
