Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.894% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a COC(=O)CSc1nnc(C)n1-c1cccc(C#N)c1
b O=C(CCl)N(c1ccccc1)c1c[nH]c2ccccc12
Answer: a. COC(=O)CSc1nnc(C)n1-c1cccc(C#N)c1
