Margaret Was So Excited to Share the Great News with Her

Margaret was so excited to share the great news with her friends! She had just taken the Wechsler Intelligence Test and scored a 100. Being a 'C' student, Margaret was thrilled to think that she had actually earned the perfect score of 100! Margaret's teacher informed her that

A) the Wechsler scale only measures verbal intelligence, so her score is only for one aspect of intelligence
B) her score is a quotient, and therefore an individual score that was not linked to actual intelligence
C) IQ test scores are often inflated and unreliable so she may not score a 100 again
D) her score is relative to others her age and a score of 100 is the average performance
