Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 0.504% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1ccc(-c2nc(C#N)c(N3CCN(C(=O)c4ccco4)CC3)o2)cc1OC
b: CC1(C)Cc2c(c(-c3ccco3)nc3sc4c(NCCN5CCOCC5)ncnc4c23)CO1
c: Cc1ccc(NC(=O)CSc2cccc[n+]2[O-])c([N+](=O)[O-])c1
d: COCCn1nnnc1C(c1ccc(C(F)(F)F)cc1)N1CCOCC1
Answer: a. COc1ccc(-c2nc(C#N)c(N3CCN(C(=O)c4ccco4)CC3)o2)cc1OC
