Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 2.251\% 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: O=S(=O)(c1cccc(-c2nc3ccccc3s2)c1)N1CCCC1
b: CCN(c1ccc(C(=O)CN2C(=O)NC3(CCOc4ccccc43)C2=O)cc1)S(C)(=O)=O
Answer: a. O=S(=O)(c1cccc(-c2nc3ccccc3s2)c1)N1CCCC1
