Task: Answer the multiple choice question.
Question: Which compound has a -1.170% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COc1ccccc1C(=O)OCn1nnc2ccccc2c1=O
b Cl.O=C1NCC2(CCN(CCc3ccccc3)CC2)O1
c CC1CC=C2C(C#N)=C(N)C(C#N)(C#N)C(c3cccs3)C2C1
d COc1ccc2c(c1OC)C(=O)OC2c1c(O)n(Cc2ccc(F)cc2)c(=O)[nH]c1=O
Answer: a. COc1ccccc1C(=O)OCn1nnc2ccccc2c1=O
