Task: Answer the multiple choice question.
Query: Which drug has a 15.875\% 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) COc1ccc(C(=O)/C=C/Sc2nc3ccccc3o2)cc1
b) CCCOc1ccc(CCC(=O)N/N=C/c2ccc([N+](=O)[O-])o2)cc1
Answer: a. COc1ccc(C(=O)/C=C/Sc2nc3ccccc3o2)cc1
