Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.326\% 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 O=C(Nc1cccc(-c2nc3ccccc3[nH]2)c1)c1cccc(NC(=O)c2ccco2)c1
b CCCN(CC1CC1)C(=O)CCc1nnc(C(OC)c2ccccc2)o1
Answer: a. O=C(Nc1cccc(-c2nc3ccccc3[nH]2)c1)c1cccc(NC(=O)c2ccco2)c1
