Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.246% 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(NNC(=O)c1ccc([N+](=O)[O-])cc1)c1ccc(F)cc1
(b) Cc1sc(NC(=O)CSc2nnc(-c3ccc(F)cc3)o2)c(C#N)c1C
(c) COc1ccc(-c2cc3c(=O)n(CC(=O)NCc4ccccc4F)ncn3n2)cc1
(d) CCn1c(SCC(=O)NC(=O)NCc2ccco2)nnc1-c1cccs1
Answer: a. O=C(NNC(=O)c1ccc([N+](=O)[O-])cc1)c1ccc(F)cc1
