Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.505\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) O=C(CSc1nnc2ncccn12)Nc1cccc2ccccc12
(b) O=c1[nH]c(NCc2ccccc2)nc2c1CCCC2
Answer: b. O=c1[nH]c(NCc2ccccc2)nc2c1CCCC2
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
