Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.601\% 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: CCCCCC(=O)Nc1ccccc1N1CCN(c2ccccc2)CC1
b: Cn1c(=O)n(C)c2cc(NS(=O)(=O)c3ccc(C(C)(C)C)cc3)ccc21
c: O=C(O)CSCc1ccc(Cl)cc1
d: CC(CC(=O)O)Nc1ccccc1O
Answer: c. O=C(O)CSCc1ccc(Cl)cc1
