Problem statement: Answer the multiple-choice question.
Question: Which drug has a 14.484\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. COC(=O)CC1C(=O)NC(C)=C1C(=O)OC
b. COc1ccc(C(C(=O)NC(C)(C)C)N(Cc2ccccc2)C(=O)CCC(=O)Nc2cc(C)on2)cc1
Answer: a. COC(=O)CC1C(=O)NC(C)=C1C(=O)OC
