Which of these statements is subjective?

where are the statements?

San Francisco is the coolest city in America.

Explanation:

Subjective sentences are from the opinion of the speaker.

-"San Francisco is the coolest city in America." is subjective because the speaker is saying an opinion on San Fransisco. It cannot be backed up by facts.

Objective sentences are the opposite of subjective sentences. They can be backed up by evidence. B, C, and D can be proven by evidence, and they also have no opinion in them. Therefore, B, C, and D, are objective sentences.

Option A, San Francisco is the coolest city in America, would be your best choice.
