Task: Answer the multiple-choice question.
Question: Which compound exhibits a -7.068\% 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.) O=C(Nc1ccccn1)c1cc(-n2cnnc2)ccc1Cl
b.) CCOc1cc(/C=N/Nc2nnc(C)n2N)ccc1O.Cl
c.) CCOc1ccc(-c2cc3nc(C4CCN(C(=O)OC(C)(C)C)CC4)c(C(=O)O)cn3n2)cc1
d.) CC(C)CN(CC(C)C)C(=O)Nc1cccc([N+](=O)[O-])c1
Answer: a. O=C(Nc1ccccn1)c1cc(-n2cnnc2)ccc1Cl
