Problem statement: Answer the multiple choice question.
Query: Which drug has a 8.779\% 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 O=C(C1=C(O)C(=O)N(CCOCCO)C1c1cccs1)c1cccs1
b CN1CCN(c2ccc(NC(=O)c3sc4ccccc4c3Cl)cc2)CC1
Answer: a. O=C(C1=C(O)C(=O)N(CCOCCO)C1c1cccs1)c1cccs1
