Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 12.972\% 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: N#C/C(=C\c1cccnc1)c1nc2ccccc2[nH]1
b: CC1C/C(=N\NC(=O)c2ccc([N+](=O)[O-])cc2)CC(C)(C)C1
Answer: a. N#C/C(=C\c1cccnc1)c1nc2ccccc2[nH]1
