Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.384\% 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] NS(=O)(=O)c1ccc(NC(=O)c2ccc(S(=O)(=O)N3CCc4ccccc43)cc2)cc1
[b] O=S(=O)(c1ccc(-n2cnnn2)cc1)N1CCN(c2ccccc2F)CC1
[c] CC1(C)CC(=O)C(C(=O)c2ccccc2)C(=O)C1Cl
Answer: c. CC1(C)CC(=O)C(C(=O)c2ccccc2)C(=O)C1Cl
