Select the most appropriate option to fill in the blank.

Our salaries ______ increased over the years.

have

The most appropriate option to fill in the blank is:

☀ have

The sentence would read: "Our salaries have increased over the years."

Explanation: The sentence is in the present perfect tense, which requires the auxiliary verb "have" before the past participle form of the main verb "increased." The other options don't fit the context:

• Are: This is the present tense of the verb "to be" and doesn't match the tense of the sentence.

• Has: This is the third person singular form of the verb "to have" and doesn't match the subject "our salaries."

• Is: This is the present tense of the verb "to be" and doesn't match the tense of the sentence.
