Question

Dentify the complete adjective clause. Take this letter that I have written to the post office

Answer 1

Hey there,

Your question/statement states: Identify the complete adjective clause. Take this letter that I have written to the post office.

The word $\boxed{adjective \ clause}$ means "to have group of words (with a subject) and also a verb with a great description."

From looking at the sentence above, " Take this letter that I have written to the post office". The group of words that has a subject and also a verb would be (That I have written).The subject would be (that i) and the verb would be (written). 

Your correct answer would be (that I have written).

Hope this helps.
