Task: Answer the multiple choice question.
Query: Which drug exhibits a -6.410% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C(Nc1ccc2nc(-c3cccnc3)[nH]c2c1)c1ccco1
b) O=C(Nc1ccc(N2CCOCC2)c([N+](=O)[O-])c1)c1ccco1
c) CCn1c2ccccc2c2cc(NC(=O)c3cccc([N+](=O)[O-])c3C)ccc21
d) O=c1cc(CN2CCN(c3ccccc3F)CC2)c2cc3c(cc2o1)CCCC3
Answer: b. O=C(Nc1ccc(N2CCOCC2)c([N+](=O)[O-])c1)c1ccco1
