Task: Answer the MCQ question.
Question: Which drug exhibits a 4.746\% 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) C/C(CC(=O)Nc1ccc(Cl)c(Cl)c1)=N\NC(=O)Cc1ccccc1
(b) CCCCCOC(=O)Cc1c(C)nc(-c2ccccc2)[nH]c1=O
Answer: a. C/C(CC(=O)Nc1ccc(Cl)c(Cl)c1)=N\NC(=O)Cc1ccccc1
