Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.668\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CCOc1cc(CNc2ccc3c(c2)CCC3)ccc1OC
b. O=C1NNC(c2ccccc2)=N/C1=C\c1ccccc1
Answer: b. O=C1NNC(c2ccccc2)=N/C1=C\c1ccccc1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
