Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.384\% 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) Cc1ccnc(-n2c(-c3ccco3)nc3ccccc3c2=O)c1
b) Cc1sc2nc(CSc3ccc([N+](=O)[O-])cc3)[nH]c(=O)c2c1C
Answer: a. Cc1ccnc(-n2c(-c3ccco3)nc3ccccc3c2=O)c1
