Can yall plz i dont rally get this

Write the prefix’s meaning and then write the word next to it. If this wasn’t clear, look at the example below.

For number 15, for example, you can write the prefix’s meaning, which is re- because of the word “again,” and you could then write the word “submit.” This would leave you with the word “resubmit.”

Aand c are my best guess because these make sense to me
