Task: Answer the multiple choice question.
Question: Which compound has a 15.285\% 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, b, or c without using any other words.
Options:
a Cn1c(=O)c2sccc2n(Cc2ccc(Br)cc2)c1=O
b CC(CCc1ccccc1)NC(=O)CCC(=O)N1CCC(C(=O)O)CC1
c COC(=O)[C@H](C)NC(=O)NCCC1=CCCCC1
Answer: a. Cn1c(=O)c2sccc2n(Cc2ccc(Br)cc2)c1=O
