Task: Answer the multiple-choice question.
Query: Which compound has a 11.449\% 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=c1c2cc(Cl)ccc2nc(-c2ccc([N+](=O)[O-])cc2)n1O
(b) O=C(CCn1nnc(-c2cccs2)n1)NCc1ccccc1Cl
(c) O=C(N1CCOCC1)n1nnc2ccccc21
(d) O=c1c2ccccc2nc(-c2ccc(Cl)c(Cl)c2)n1O
(e) Cc1c(Cl)cccc1N(CC(=O)N1CCCCCC1)S(C)(=O)=O
Answer: a. O=c1c2cc(Cl)ccc2nc(-c2ccc([N+](=O)[O-])cc2)n1O
