Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.572% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. COC(=O)[C@@H](NC(=O)Nc1ccccc1F)C(C)C
b. C=CCNC(=S)N1CCC(C(=O)c2ccc3c(c2)OCCO3)CC1
Answer: a. COC(=O)[C@@H](NC(=O)Nc1ccccc1F)C(C)C
