Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.356\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) NC(=O)Cc1ccc2c(c1)[nH]c1ccccc12
b) O=C(CCCc1nc2ccccc2s1)Nc1nccs1
c) O=C1CCN(S(=O)(=O)c2ccccc2)CCN1CCOCc1ccccc1
Answer: a. NC(=O)Cc1ccc2c(c1)[nH]c1ccccc12
