Task: Answer the multiple choice question.
Query: Which compound exhibits a -25.237\% 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) COc1cc(OC)cc(C(=O)NCC(=O)Nc2ccc(-c3ccccc3)cc2)c1
(b) O=C(c1ccc([N+](=O)[O-])cc1)N1CCC(Cc2ccccc2)CC1
(c) Cl.NS(=O)(=O)c1ccc(CCNCC#Cc2ccccc2)cc1
(d) CCCC(=O)Nc1nc(C)c(-c2csc(Nc3ccccc3C)n2)s1
(e) S=C(NCCCN1CCOCC1)N1CCN(c2nc(-c3ccc(Cl)cc3)cs2)CC1
Answer: b. O=C(c1ccc([N+](=O)[O-])cc1)N1CCC(Cc2ccccc2)CC1
