Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 7.885\% 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) O=C(COC(=O)c1n[nH]c2ccccc12)Nc1ccccc1
(b) COc1ccc(OCc2cc(C(=O)NC(C)Cn3cncn3)no2)c(Cl)c1
(c) Cc1nc(C(=O)NC2CCOCC2)sc1C1(C)CC(c2cccc([N+](=O)[O-])c2)=NO1
(d) O=C(Nc1ccc(Br)cc1)NC1CCCCCCC1
(e) O=[N+]([O-])c1cc2c(cc1CN1CCN(c3ccc(F)cc3)CC1)OCO2
Answer: e. O=[N+]([O-])c1cc2c(cc1CN1CCN(c3ccc(F)cc3)CC1)OCO2
