Task: Answer the multiple choice question.
Question: Which drug exhibits a -5.461% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CCOC(=O)c1[nH]c(=O)[nH]c1COC(=O)c1cc2ccccc2o1
b) CC(=O)Oc1cccc(/C=C2\Sc3ccccc3C2=O)c1
Answer: a. CCOC(=O)c1[nH]c(=O)[nH]c1COC(=O)c1cc2ccccc2o1
