Task: Answer the multiple-choice question.
Question: Which compound exhibits a -1.836\% 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(C2C(C#N)=C(N)N(c3cccnc3)C3=C2C(=O)CC(C)(C)C3)cc1OC
b O=C(NC(=O)N1CCCC1)c1csnn1
Answer: a. COc1ccc(C2C(C#N)=C(N)N(c3cccnc3)C3=C2C(=O)CC(C)(C)C3)cc1OC
