Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -17.419\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a CCCCN=Cc1c(O)n(-c2c(C)cc(C)cc2C)c(=O)[nH]c1=O
b Cc1ccccc1NC(=O)C1CCN(C(=O)NC2CCCCC2)CC1
Answer: a. CCCCN=Cc1c(O)n(-c2c(C)cc(C)cc2C)c(=O)[nH]c1=O
