Task: Answer the multiple-choice question.
Query: Which drug exhibits a 14.897\% 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, d, or e without using any additional words.
Options:
(a) COC(=O)c1sccc1N(C)S(C)(=O)=O
(b) O=C(COC(=O)c1ccccn1)c1cccc(Br)c1
(c) CCOc1ccccc1CN1C(=O)c2ccccc2C1C(=O)NCC1CCCO1
(d) Cc1nc2cc(Nc3ccncc3)ccc2s1
(e) Cc1cc(/C=C2\SC(=S)N(C)C2=O)c(C)n1-c1ccccc1O
Answer: a. COC(=O)c1sccc1N(C)S(C)(=O)=O
