Problem statement: Answer the multiple choice question.
Query: Which drug has a -0.684% 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 CCOC(=O)c1c(NC2OC(=O)c3c2ccc(OC)c3OC)sc(C(=O)OC(C)(C)C)c1C
b CCCCC(=O)Nc1sc(C(=O)N(CC)CC)c(C)c1C(=O)OC
Answer: a. CCOC(=O)c1c(NC2OC(=O)c3c2ccc(OC)c3OC)sc(C(=O)OC(C)(C)C)c1C
