Problem statement: Answer the multiple-choice question.
Query: Which drug has a 16.248\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=[N+]([O-])c1ccc(Nc2ccccn2)c([N+](=O)[O-])c1
b: COc1ccc(N2CCN(C(=O)CNS(=O)(=O)c3ccc(Br)s3)CC2)cc1
c: O=C(Nc1ccc(Br)cn1)C1CCN(S(=O)(=O)c2cccs2)CC1
d: CCCCCCCN=CC1=C(O)CC(c2ccccc2)CC1=O
Answer: a. O=[N+]([O-])c1ccc(Nc2ccccn2)c([N+](=O)[O-])c1
