Task: Answer the multiple choice question.
Question: Which drug exhibits a -17.739% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. O=C(c1cccnc1Cl)N(Cc1ccccc1)Cc1ccccc1
b. COc1ccc(C2C(C(=O)Nc3cc(C)on3)c3ccccc3C(=O)N2C)cc1OC
Answer: a. O=C(c1cccnc1Cl)N(Cc1ccccc1)Cc1ccccc1
