Answer:
C. Anna tried to hold back the dog, but she just was not strong enough for the bulk, power, and movement of the dog.
Step-by-step explanation:
A revision is when a given sentence or any given passage is rewritten in a better form. This can involve changes in the words, or voice or tense, or even the structure of the whole sentence.
In the given sentence, the proper noun is used after the pronoun. Instead of using the pronoun to start the sentence, if we use the proper noun "Anna" to start the sentence, then the sentence is made easier to understand and also who is being talked about. Also, changing the structure of the sentence by rearranging certain words will make the sentence better in form and construction.
Thus, the revised sentence will be option C.
