Task: Answer the multiple-choice question.
Query: Which drug has a 4.753\% 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(C(O)C(=O)c2c[nH]c3ccccc23)N2CCN(c3ccccc3)CC2)cc1
b: CC1=C(C(=O)O)N2C(=O)C(NC(=O)c3nn(C)cc3[N+](=O)[O-])C2SC1
Answer: a. COc1ccc(C(C(O)C(=O)c2c[nH]c3ccccc23)N2CCN(c3ccccc3)CC2)cc1
