Task: Answer the multiple choice question.
Query: Which compound exhibits a 0.759\% 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: O=S(=O)(Nc1ccc2c(c1)OCCO2)c1ccc(Br)s1
b: CCOc1ccc(S(=O)(=O)NCCC(=O)N2CC=C(c3ccccc3)CC2)cc1
c: COc1ccc([C@H]2[C@H]3C=CC[C@@H](C)[C@@H]3C(=O)N2Cc2ccccc2)cc1Cl
Answer: a. O=S(=O)(Nc1ccc2c(c1)OCCO2)c1ccc(Br)s1
