Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.038% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] COC(=O)C1=CN(Cc2ccc(OC)cc2)C=C(C(=O)OC)C1c1cc(OC)c(OC)c(OC)c1
[b] COC/C=C/C1=CC2=CC(=O)C(C)(OC(=O)c3cnc4ccccc4n3)C(=O)C2=CN1CCCCO
Answer: b. COC/C=C/C1=CC2=CC(=O)C(C)(OC(=O)c3cnc4ccccc4n3)C(=O)C2=CN1CCCCO
