Task: Answer the multiple choice question.
Question: Which drug has a -7.052% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CC(=O)Oc1ccc(C(=O)Nc2cc(C)ccc2NC(=O)COc2ccccc2)cc1
b: COC(=O)c1ccc2c(c1)N(C)CCS2
c: CCOC(=O)C1CCN(c2cc(=O)n(-c3ccccc3Cl)c(=O)[nH]2)CC1
Answer: b. COC(=O)c1ccc2c(c1)N(C)CCS2
