Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.016\% 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. Cn1nc(C(=O)Nc2cccc(S(N)(=O)=O)c2)c2ccccc2c1=O
b. COC(=O)c1c(NC(=O)CN2CCN(c3ccccc3)CC2)c2c(C)cccc2n1C
Answer: b. COC(=O)c1c(NC(=O)CN2CCN(c3ccccc3)CC2)c2c(C)cccc2n1C
