Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.618\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) Cc1cccc(NCC(=O)N/N=C\c2ccccn2)c1
b.) O=C(NCCc1ccc([N+](=O)[O-])cc1)c1ccccc1
c.) CCN1CCN(CCNC(=O)Nc2ccc([N+](=O)[O-])cc2)CC1
d.) CCN1CCN(c2oc(COc3ccc(-c4ccccc4)cc3)nc2C#N)CC1
Answer: a. Cc1cccc(NCC(=O)N/N=C\c2ccccn2)c1
