Task: Answer the multiple choice question.
Query: Which drug has a -26.877% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C(C1CC1)N1N=C(c2ccccc2)CC1(O)C(F)(F)C(F)(F)F
b) CCC(=O)N1CCN(c2ccc(NC(=O)c3ccc(Br)o3)cc2)CC1
Answer: b. CCC(=O)N1CCN(c2ccc(NC(=O)c3ccc(Br)o3)cc2)CC1
