Task: Answer the multiple choice question.
Query: Which compound exhibits a -9.493% 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 or b without using any additional words.
Options:
a: C=CCn1cnc2c(c1=O)c1nc3ccccc3nc1n2-c1ccc(C)cc1
b: Cc1ccc(NC(=O)N2CCCC(c3nc(-c4ccc(F)cc4)no3)C2)cc1
Answer: a. C=CCn1cnc2c(c1=O)c1nc3ccccc3nc1n2-c1ccc(C)cc1
