Task: Answer the multiple choice question.
Question: Which compound exhibits a -5.351% 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 other words.
Options:
a. CCOC(=O)C1=C(COC(=O)CNC(=O)c2cc(OC)c(OC)c(OC)c2)NC(=O)NC1C
b. Cc1cc(Br)ccc1OCCCCN1CCCCC1.O=C(O)C(=O)O
Answer: a. CCOC(=O)C1=C(COC(=O)CNC(=O)c2cc(OC)c(OC)c(OC)c2)NC(=O)NC1C
