Task: Answer the multiple-choice question.
Query: Which compound has a 5.541\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(O)C1=CC[C@@H](c2ccc(Cl)cc2)N(S(=O)(=O)c2ccc(Cl)cc2)[C@H]1c1ccccc1
b: CC1CCCN(C(=O)CCNS(=O)(=O)c2ccc(Br)cc2)C1
c: COCCN(C(=O)COC(=O)c1cnc(C)cn1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
d: CCOc1cccc(C(=O)N(Cc2cccc(F)c2)C2CCS(=O)(=O)C2)c1
Answer: a. O=C(O)C1=CC[C@@H](c2ccc(Cl)cc2)N(S(=O)(=O)c2ccc(Cl)cc2)[C@H]1c1ccccc1
