Task: Answer the multiple choice question.
Query: Which drug exhibits a -15.167\% 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(NCC1CCCO1)c1cccc(N2CCCC2=O)c1
b CC(C)Cc1ccccc1O
c O=C(CN(Cc1ccco1)C(=O)Cn1nnc(-c2ccc(F)cc2)n1)NC1CCCC1
d O=C(Cn1c(N2CCN(c3ccccc3)CC2)nc2ccccc21)c1ccccc1
e NC(=O)C1CCN(c2cc(N3CCOCC3)ccc2[N+](=O)[O-])CC1
Answer: d. O=C(Cn1c(N2CCN(c3ccccc3)CC2)nc2ccccc21)c1ccccc1
