Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES COc1ccc(-c2csc3ncnc(N4CCN(S(=O)(=O)c5ccc(C)cc5)CC4)c23)cc1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a. 5.191
b. -17.286
c. 6.397
Answer: a. 5.191\%.
