Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.801\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) CN1C(=O)N(C)C(=O)C2(Cc3cc([N+](=O)[O-])ccc3N(C)C2c2ccccc2)C1=O
b.) CCN1CCN(c2nc(N(C)c3ccccc3)nc(N)c2[N+](=O)[O-])CC1
c.) CC(=O)N1CCN(c2ccc(NC(=O)COc3ccc(Cl)cc3Cl)cc2)CC1
d.) COc1ccc(-c2cccc(NS(=O)(=O)c3cc([N+](=O)[O-])ccc3Cl)c2)nn1
Answer: a. CN1C(=O)N(C)C(=O)C2(Cc3cc([N+](=O)[O-])ccc3N(C)C2c2ccccc2)C1=O
