Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.256\% 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.) CCCSCCCNC(=O)c1cc2c(s1)CS(=O)(=O)C2
b.) COC(=O)C1=C(C)N(Cc2ccc3c(c2)OCO3)C(=O)C1
Answer: b. COC(=O)C1=C(C)N(Cc2ccc3c(c2)OCO3)C(=O)C1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_1uM#}{herg_central_at_1uM__units} {herg_central_at_1uM__names__noun}?
