Problem statement: Answer the multiple choice question.
Question: Which drug has a -0.520\% 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: CCOC(=O)c1c(C)[nH]c(C(=O)COC(=O)/C=C/c2ccc3c(c2)OCO3)c1C
b: CCN(CC)S(=O)(=O)c1ccc(OC)c(NC(=O)CSc2cc(C)ccc2C)c1
Answer: a. CCOC(=O)c1c(C)[nH]c(C(=O)COC(=O)/C=C/c2ccc3c(c2)OCO3)c1C
