Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.621\% 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) COc1cc2c(cc1OC)C(c1cccc([N+](=O)[O-])c1)N(C(=O)c1ccccc1C(=O)O)CC2
b) CCOc1ccc(CCNC(=O)c2cccc(NC3=NC4CS(=O)(=O)CC4S3)c2)cc1OCC
Answer: a. COc1cc2c(cc1OC)C(c1cccc([N+](=O)[O-])c1)N(C(=O)c1ccccc1C(=O)O)CC2
