Explanation:

In the given sentence, we need to choose the appropriate verb forms for the verb "help" to complete the sentence correctly.

First, let's identify the base form or infinitive of the verb, which is "to help".

Next, we need to find the past indefinite form of the verb, which is "helped".

Then, we find the ing-form or present participle of the verb, which is "helping".

Finally, we have to choose the most suitable auxiliary verb form to complete the sentence. In this case, the sentence is talking about a future action, so the auxiliary verb "will" is the most suitable choice.

Therefore, the correct sentence is "Paul will help his mother about the house tomorrow."
