Problem statement: Answer the multiple-choice question.
Question: Which drug has a -0.178\% 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) CCCCN1C(=O)C(NC(C)=O)c2cc(Br)ccc21
(b) CCc1ccc(CNC(=O)C(=O)NCC2CCCO2)cc1
Answer: a. CCCCN1C(=O)C(NC(C)=O)c2cc(Br)ccc21
