Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.850% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1cc([N+](=O)[O-])ccc1NC(=O)/C=C\C(=O)O
(b) CN1c2ccsc2C(=O)/C(=C\Nc2cccc(C(F)(F)F)c2)S1(=O)=O
(c) O=C(CN1C(=O)c2ccccc2C1=O)Nc1cccc(Cl)c1
(d) O=C(Cn1cnc([N+](=O)[O-])c1)c1ccc(Cl)cc1
Answer: a. COc1cc([N+](=O)[O-])ccc1NC(=O)/C=C\C(=O)O
