Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.454\% 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 or b without using any other words.
Options:
a CCCOC(=O)c1c(NC(=O)C2CCCO2)sc(C(=O)OC)c1C
b COC(=O)c1c(NS(=O)(=O)c2cccs2)sc2c1CCCC2
Answer: a. CCCOC(=O)c1c(NC(=O)C2CCCO2)sc(C(=O)OC)c1C
