Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 12.875\% 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 other words.
Options:
(a) O=c1[nH]c(=O)c2ccccc2[nH]1
(b) Cn1c(COc2ccc(Br)cc2)nnc1SC1CCc2ccccc2C1=O
(c) Cc1ccccc1OCC(=O)NNC(=S)NC(=O)c1ccccc1[N+](=O)[O-]
Answer: a. O=c1[nH]c(=O)c2ccccc2[nH]1
