Task: Answer the multiple-choice question.
Query: Which drug exhibits a -2.473\% 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 additional words.
Options:
a: O=C(NCC(c1cccnc1)N1CCN(c2ccc(F)cc2)CC1)Oc1ccccc1
b: NC(=O)CC(NC(=O)c1ccccc1)c1ccc(NC2CCC2)c([N+](=O)[O-])c1
c: Cc1ccc(S(=O)(=O)Cc2cc(-c3ccc(Cl)cc3)no2)cc1
d: O=C(CN1CCCCC1)N1c2ccccc2Oc2ccccc21
e: CCCN(CCO)Cc1ccc(Cl)c(Cl)c1
Answer: e. CCCN(CCO)Cc1ccc(Cl)c(Cl)c1
