Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.325\% 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 or b without using any additional words.
Options:
(a) COc1cccc2sc(NC(=O)c3ccc(S(=O)(=O)N4CCOCC4)cc3)nc12
(b) CCOC(=O)/C(C#N)=C/c1ccc(OC)c(OC)c1
Answer: b. CCOC(=O)/C(C#N)=C/c1ccc(OC)c(OC)c1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
