Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 13.893\% 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) C/C(N)=C(/C#N)C(=O)CSc1nnnn1-c1ccccc1
(b) CC1CCC/C(=C\Nc2ccccc2C(=O)O)C1=O
Answer: a. C/C(N)=C(/C#N)C(=O)CSc1nnnn1-c1ccccc1
