Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.571\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCCCC(=O)Nc1ccc2c3c(cccc13)CC2
b O=C(O)C(=O)O.O=C(c1ccccc1)c1ccc(OCC(O)CNCc2cccc(Cl)c2)cc1
c CCc1ccc(OCCNc2cc(N3CCNC(C)C3)ccc2[N+](=O)[O-])cc1
d CC(NC(=O)c1cc2cc(Cl)ccc2oc1=N)c1ccccc1
e Fc1ccc(-c2nnc(-c3ccc(F)cc3)o2)cc1
Answer: c. CCc1ccc(OCCNc2cc(N3CCNC(C)C3)ccc2[N+](=O)[O-])cc1
