Task: Answer the multiple-choice question.
Query: Which drug has a 2.731\% 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(NC1CC1)C1CCC(=O)N1C1CCCC1
b) COc1ccccc1N=Nc1c(O)[nH]c(=S)[nH]c1=O
Answer: a. O=C(NC1CC1)C1CCC(=O)N1C1CCCC1
