Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.616% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(Cc1ccccc1[N+](=O)[O-])NNC(=O)c1cccs1
(b) CCOC(=O)c1cnn(CCOC(=O)Cc2cccs2)c1NC(=O)Cc1cccs1
(c) CCn1c2ccccc2c2cc(N)ccc21
Answer: a. O=C(Cc1ccccc1[N+](=O)[O-])NNC(=O)c1cccs1
