Task: Answer the multiple choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a drug with the SMILES C=CCOc1ccc(-c2nc3c(c(=O)[nH]c(=O)n3CCC)n2CCCC)cc1?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] 4.868
[b] 20.952
[c] -4.396
[d] 7.503
Answer: d. 7.503\%.
