Task: Answer the multiple-choice question.
Question: Which drug exhibits a -5.066\% human ether-à-go-go related gene (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 other words.
Options:
a: CN(C(=O)CN1CCC(NC(=O)C2CCCCC2)CC1)C1CCCCC1.Cl
b: COc1ccc2oc(C(=O)OCC(=O)NC3CCCC3)c(C)c2c1
c: O=S(=O)(NCC(c1cccnc1)N1CCN(c2ccccc2)CC1)c1cc(F)ccc1F
d: Cc1ccccc1NC(=O)/C(C#N)=C/c1ccc(-c2ccc(Cl)c(C(=O)O)c2)o1
e: CCc1ccc(C2CC(c3cccc(Cl)c3)n3nc(N)nc3N2)cc1
Answer: e. CCc1ccc(C2CC(c3cccc(Cl)c3)n3nc(N)nc3N2)cc1
