Task: Answer the multiple-choice question.
Query: Which drug exhibits a 10.316\% 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 Cl.O=C(CCN1Cc2ccccc2C1)c1ccc2c(c1)OCCO2
b COC(=O)C1=C(C)N(c2ccc(Br)cc2)C(=O)/C1=C\c1ccco1
Answer: b. COC(=O)C1=C(C)N(c2ccc(Br)cc2)C(=O)/C1=C\c1ccco1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
