Task: Answer the multiple choice question.
Query: Which compound exhibits a -0.145\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(N2CC(O)=C(c3nc(-c4ccc(F)cc4)cs3)C2=N)cc1
b: COC(=O)c1ccc2c(c1)NC(=O)C(N1CCCC1)S2
c: Cc1ccnc(NC(=O)Cn2cc([N+](=O)[O-])cn2)c1
Answer: b. COC(=O)c1ccc2c(c1)NC(=O)C(N1CCCC1)S2
