The correct answer is: A. She was given a bull dog.
The other options are incorrect because they do not accurately reflect the tense of the sentence. The sentence states that someone gave her a bulldog, which means that the action of giving the bulldog has already been completed. This is consistent with the simple past tense of the verb “gave.”
Option B, “A bulldog was given to her,” is also in the simple past tense, but it does not specify who gave the bulldog to her. This is incorrect because the sentence states that someone gave her the bulldog.
Option C, “She has been given a bulldog,” is in the present perfect tense. This tense is used to describe actions that have been completed but have an ongoing effect. In this case, the action of giving the bulldog to her has been completed, but the bulldog is still in her possession. However, this is not the meaning that the sentence is trying to convey.
Option D, “She is being given a bulldog by someone,” is in the present progressive tense. This tense is used to describe actions that are happening now or that are happening repeatedly. In this case, the action of giving the bulldog to her is not happening now, and it is not happening repeatedly. Therefore, this option is also incorrect.
In conclusion, the correct answer is: A. She was given a bull dog.
