Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.603% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) C=CCOc1nc(-c2ccncc2)nc2ccccc12
b.) O=C(NC1CCN(C(=O)c2cccc([N+](=O)[O-])c2)CC1)c1ccccc1
c.) CCOC(=O)N1CCC(N2CCN(C3CCCC3)C(CCO)C2)CC1
d.) Cc1nc2ccc(C(=O)O)cc2nc1C
Answer: a. C=CCOc1nc(-c2ccncc2)nc2ccccc12
