The correct answer is Option (3) → (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
The IQ score of a person is interpreted with the classification of people on the basis of IQ; the mean IQ in a population is 100.

(C) Low average — this matches (I) 80 - 89. It is the band just below the average range.
