Answer:
Mary Jean and Beth <u>volunteered</u> for the past five years at a local shelter for abused pets.
Explanation:
In the given sentence, the action/ verb is something that's done in the past. This is identified by the phrase "for the past five years", meaning it is an action that's been done in the past, that happened some years before the present. Therefore, the verb "volunteer" will be used on the past form "volunteered".
So, the newly revised sentence will become-
Mary Jean and Beth <u>volunteered</u> for the past five years at a local shelter for abused pets.

Yes, it is B, it is a defining relative clause, notice that without the relative clause the sentence feels empty <em>Only the players are going to get sunburned today. </em>
Defining relative clauses use <em>who/that</em> for people, <em>which/that</em> for things and they are not delimited by commas.
<em>Only the people that/who arrived first can enter.</em>
<em>This the house that/which I used to live in.</em>
Non-defining clauses are just extra comments, optionally they can be removed about the previous noun/pronoun, they are separed by commas and <em>that</em> cannot be used.
<em>Mary,who wears glasses, lives next door.</em>
<em>This country, which was a super power in the past, is still facing amajor economic crisis.</em>
