Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 2.749\% 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=C(N/N=C/C(Cl)=C/c1ccccc1)c1cnccn1
b.) CCOc1ccc(C(=O)NC2CC3CCCC(C2)N3Cc2ccccc2)cc1
c.) Cc1cc([N+](=O)[O-])ccc1N=Nc1c(N)[nH]n(-c2ccccc2)c1=O
d.) Cc1cnc(C(=O)OCC(=O)Nc2ccc(Cl)cc2Cl)cn1
Answer: a. O=C(N/N=C/C(Cl)=C/c1ccccc1)c1cnccn1
