Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.123\% 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 COc1ccc(CNC(=O)C2CCCN2C)cc1OC
b N#Cc1c(C(F)(F)F)cc(Cc2ccccc2)nc1SCC(=O)NCC(=O)O
c O=C(CCS(=O)(=O)Cc1ccccc1)Nc1nncs1
Answer: a. COc1ccc(CNC(=O)C2CCCN2C)cc1OC
