Problem statement: Answer the multiple choice question.
Question: Which compound has a 1.874\% 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=C(NCCCN1CCCCCC1)C1CC(=O)N(C2CCCC2)C1
b.) O=C(NCCc1ccc(Cl)cc1)C1CCC(CNc2c(N3CCCCC3)c(=O)c2=O)CC1
Answer: a. O=C(NCCCN1CCCCCC1)C1CC(=O)N(C2CCCC2)C1
