Problem statement: Answer the multiple choice question.
Question: Which drug has a 12.532\% 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 COc1nc(Nc2ccc(OC)c(Cl)c2)nc(OC)n1
b CN(C)c1ncc(CN2CCC(C(=O)Nc3ccc(-n4cccn4)cc3)CC2)s1
c COc1ccc(C(=O)CC(Nc2ccc([N+](=O)[O-])cc2)c2ccc(OC)cc2)cc1
d COC(=O)Cc1[nH]c(Cl)nc1C(N)=O
Answer: a. COc1nc(Nc2ccc(OC)c(Cl)c2)nc(OC)n1
