Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.551\% 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) Cc1[nH]nc2c1C(=O)CC(C)(C)C2
(b) O=C(CSc1ccccc1C(=O)O)NC1CCCCCCC1
Answer: a. Cc1[nH]nc2c1C(=O)CC(C)(C)C2
