Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.262\% 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) COc1ccc2c(c1)sc1nc(O)c(-c3c(C)cc(C)cc3C)c(=O)n12
(b) CNC(=O)C(NC(=O)c1ccccc1)=C(C)C
(c) CCN1C(=O)NC2C1N(S(C)(=O)=O)CCN2S(C)(=O)=O
Answer: b. CNC(=O)C(NC(=O)c1ccccc1)=C(C)C
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
