Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 20.125\% 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 CCC(=O)c1cn(CC(=O)Nc2cccc(OC)c2)c2ccccc12
b CCOC(=O)C1=C(O)/C(=C\c2cccs2)N=C1C
Answer: a. CCC(=O)c1cn(CC(=O)Nc2cccc(OC)c2)c2ccccc12
