Task: Answer the multiple-choice question.
Question: Which compound exhibits a 17.700\% 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 additional words.
Options:
a: Cc1ccc(S(=O)(=O)n2c(C)nc3ccccc32)cc1
b: CCc1nnc(NC(=O)CSc2nnc(Cc3ccc(OC)cc3)o2)s1
c: O=C(OCCOc1ccc(Br)cc1)c1ccc(Cl)nc1
Answer: c. O=C(OCCOc1ccc(Br)cc1)c1ccc(Cl)nc1
