Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.418\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) Cc1occc1C(=O)N/N=C/c1cccnc1
b.) CCc1cc([N+](=O)[O-])cc(CC)c1N
