Hello. This question is incomplete. The full question is:

"In this exercise, find the sentence with the correctly embedded question.  

A. I was wondering if you knew what time is it. b. Please tell me what your plans are after you graduate. c. Have you decided what are you going to order from the menu"

c. Have you decided what are you going to order from the menu?

Explanation:

Among all the options, the only one that presents a question is the letter C. The other options, although they seem like a question, are not.

In letter A the speaker said "I was wondering if you knew what time is it". This sentence does not present a question, but an affirmation, where the speaker states that he wondered if his friend knew what time it was. The letter B, in turn, also does not represent a question, but a request, where the speaker asks his friend to comment on his plans.

The letter C, however, presents a question. The speaker wants to know the question if the friend has already decided on the menu options. In addition, we can see the presence of a question mark (?) At the end of the sentence. The interrogation is only used at the end of questions.

answer; the above statement is (true);
