Identify the sentence with correct pronoun agreement.

(a) I know who parks his car illegally in the stall reserved for the provost.

(b) I know whom parks his car illegally in the stall reserved for the provost.

(c) Everyone at the building permit office wanted their application to be processed within a few working days.

(d) Everyone at the building permit office wanted their applications to be processed within a few working days.

I'm undecided between (c) and (d): Since speaking about everyone should applications be singular or plural?? (c) sounds better to me but is it correct in grammar?

Get down to basics again:

who (s) ... his (s)

whom (s, but object form) ... (doesn't matter!)

everyone (s) ... their (pl)

everyone (s) ... their (pl)

It's A.

The correct sentence with pronoun agreement is (d) "Everyone at the building permit office wanted their applications to be processed within a few working days."

In this sentence, the pronoun "their" agrees with the plural noun "applications." When using the word "everyone," it is important to use plural pronouns that match the number of the noun they are referring to. In this case, since we are talking about multiple applications belonging to multiple individuals, the plural pronoun "their" is the correct choice.

Option (c) "Everyone at the building permit office wanted their application to be processed within a few working days" is grammatically incorrect because it uses the singular noun "application" with the plural pronoun "their." This creates a pronoun agreement error since the pronoun "their" should be matched with the plural noun "applications."

So, the correct sentence is (d) "Everyone at the building permit office wanted their applications to be processed within a few working days."
