Task: Answer the multiple-choice question.
Query: Which drug has a 5.349\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COC(=O)CC/C(O)=C1\C(=O)CC(C)(C)CC1=NCc1nc2ccccc2[nH]1
b: CCOCCCNS(=O)(=O)c1ccc(NC(=O)N2c3ccccc3Sc3ccccc32)cc1
Answer: a. COC(=O)CC/C(O)=C1\C(=O)CC(C)(C)CC1=NCc1nc2ccccc2[nH]1
