Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 21.027\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) COC(=O)CC(NS(=O)(=O)c1cccs1)c1ccccc1Cl
(b) Cc1cc(C)c(N=C2SCC(=O)N2Cc2ccco2)c(C)c1
Answer: a. COC(=O)CC(NS(=O)(=O)c1cccs1)c1ccccc1Cl
