Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.457\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) O=C(CC1NCCc2ccccc21)Nc1cccc(Cl)c1
b.) CN(Cc1ccc(Cl)cc1Cl)C(=O)c1cc(=O)c2ccccc2o1
c.) CN(C)c1ccc(C2SCCN2C(=O)c2ccc([N+](=O)[O-])cc2)cc1
d.) O=C(Cc1c[nH]c2ccccc12)Nc1nccs1
e.) Cc1ccc(C)c(N=Cc2cc3c(cc2[N+](=O)[O-])OCO3)c1
Answer: a. O=C(CC1NCCc2ccccc21)Nc1cccc(Cl)c1
