Task: Answer the multiple-choice question.
Query: Which compound exhibits a 12.876\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) CCCCN1C(=O)C(NC(C)=O)c2ccccc21
(b) CN1C(=O)c2ccccc2NC(=O)[C@]12O[C@@H]2c1ccccc1
(c) COCCN1C(=O)NC(=O)/C(=C\c2ccc(Br)cc2)C1=O
(d) CCOc1[nH]n(-c2ccc(Cl)cc2)c(=O)c1C=Nc1ccc(Cl)cc1
(e) COc1ccccc1C(=O)COC(=O)c1cc(=O)[nH]c2ccccc12
Answer: c. COCCN1C(=O)NC(=O)/C(=C\c2ccc(Br)cc2)C1=O
