The correct answer is: B. was overwhelmed/saved
The sentence is in the past tense, so the correct verb tenses to use are the past simple and the past participle. The past simple is used to describe actions that happened at a specific time in the past, and the past participle is used to form the perfect tenses. In this case, the perfect tenses are used to describe actions that happened before another action in the past.
In the first part of the sentence, the speaker is describing how they felt when they first arrived at State University. They say that they were “overwhelmed” by the size of the campus. This means that they felt a sense of confusion and anxiety because they were in a new and unfamiliar place.
In the second part of the sentence, the speaker is describing how they were saved from their confusion. They say that they found three helpful people who “saved” them. This means that the people helped the speaker to feel less confused and more comfortable in their new surroundings.
The only answer choice that uses the correct verb tenses is B. was overwhelmed/saved. The other answer choices use either the present tense or the future tense, which are not correct for this sentence.
