Task: Answer the multiple choice question.
Query: Which drug exhibits a 17.676\% 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, c, or d without using any additional words.
Options:
a: Cc1cc(=O)[nH]c2ccc(S(=O)(=O)N3CCOCC3)cc12
b: COc1ccc(-c2cc(C(=O)NCC3CCCO3)on2)cc1OC
c: CC(C)(C)c1ccc(C(=O)Nc2ccccc2Cl)cc1
d: O=C(CSc1ccc(-c2ccccn2)nn1)Nc1ccccc1
Answer: c. CC(C)(C)c1ccc(C(=O)Nc2ccccc2Cl)cc1
