Question

Which personal pronoun agrees with its antecedent and correctly completes the sentence?

Answer 1

The sentence would be "Everybody will have a chance to pick out their own souvenir," so the answer would be D. their. :)

Answer 2

Their because it sounds a lot better than all the other choices. His or Her would work probably, but their is your best bet. That their means they own it, also. 

Hope this helps! :)
