Detailed answer

In this sentence, there is a preposition missing so we add the word "of" so the weight of the apple was not measured correctly.

• The sentence now is a grammatically appropriate sentence that has a special meaning.
• The sentence now conveys that the weight of the apple was not measured the right way.
• All the other words may make the sentence a grammatically wrong sentence or a sentence that is incorrect.
