Task: Answer the multiple-choice question.
Question: Which drug has a -2.252% 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 COc1ccc(C2C(C(=O)NCC3CCCO3)CCC(=O)N2c2ccc3c(c2)OCO3)cc1
b C=CCSc1nnc(-c2ccccc2NC(C)=O)c(=O)[nH]1
c CCN1C=C(C(=O)OC)C(c2cccc(C)c2)C(C(=O)OC)=C1
d Cl.O=C1CN=C(Nc2ccccc2)N1Cc1cccs1
Answer: c. CCN1C=C(C(=O)OC)C(c2cccc(C)c2)C(C(=O)OC)=C1
