Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 9.665\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C(Nc1cccc(C(=O)N2CCOCC2)c1)c1cncc(Br)c1
b COc1ccccc1C(=O)NC(=O)CSc1nncn1C
Answer: a. O=C(Nc1cccc(C(=O)N2CCOCC2)c1)c1cncc(Br)c1
