Question

Quizplus · Accepted Answer

"Simon′s" is singular. We can eliminate the plural pronoun "theirs".
his - singular
theirs - plural
it - singular
mine - singular
The "'s" in "Simon's" tells us that we need to use the possessive case - the case we use whenever we want to show possession.
his - possessive
it - objective
mine - possessive
It is also in the third-person because we are talking about Simon. We can eliminate the first-person pronoun "mine."
his - third-person
mine - first-person
"His" is third-person, singular and in the possessive case, so it is the correct answer.
