Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 0.903\% 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 additional words.
Options:
a: CCOC(=O)C(=O)NCC(c1cccs1)S(=O)(=O)c1ccc(Cl)cc1
b: COc1ccc(N2CCN(C(c3cccs3)C(C)NS(=O)(=O)c3ccccc3)CC2)cc1
Answer: a. CCOC(=O)C(=O)NCC(c1cccs1)S(=O)(=O)c1ccc(Cl)cc1
