Task: Answer the multiple choice question.
Query: Which compound exhibits a 20.350\% 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 additional words.
Options:
a: CCOC(=O)C(NC(=O)c1ccccc1)(Nc1cc(C)on1)C(F)(F)F
b: O=C(NC1CCN(Cc2ccccc2)CC1)c1cccc(S(=O)(=O)Nc2ccc(Br)cc2)c1
c: CN(C)c1ccc(NC(=O)c2cnsn2)cc1
d: COc1ccccc1N1CCN(C(=O)C(C)N(c2ccccc2)S(C)(=O)=O)CC1
Answer: c. CN(C)c1ccc(NC(=O)c2cnsn2)cc1
