Answer:
C). Georgia O'Keeffe was a great artist, and she was inducted into the American Academy of Arts and Letters in 1962.
Explanation:
An opinion is characterized as 'a subjective belief, judgment, or perspective that an individual has formed about a specific topic, issue, person, or thing' while a fact is described as 'an objective consensus on a fundamental reality that has been agreed upon by a substantial number of experts.' An opinion may or may not be true and requires sufficient evidence or facts to establish it while a fact is an ultimate reality.
As per the question, the third statement correctly displays an opinion that is backed by a fact. It <u>shows the common belief of people that Keefe had been a wonderful artist which is supported by the factual evidence of 'her induction into Arts and Letters Academy in the year 1962' which validates the truth of the opinion</u>. Thus, <u>option C</u> is the correct answer.
