Shawna's IQ score was calculated using the formula developed by William Stern,and the result was 92.What does this indicate

A)  Shawna's mental age is greater than her chronological age. 
B)  The IQ score calculation was done incorrectly. 
C)  Shawna's mental age and chronological age are the same. 
D)  Shawna's chronological age is greater than her mental age.

According to the formula developed by William Stern, IQ = mental age/chronological age x 100. If Shawna's IQ score is 92, it means her mental age is lower than her chronological age. Therefore, her chronological age is greater than her mental age, indicating Option D. Option A cannot be determined from the given information, Option B is unlikely as the calculation was mentioned to be done using the formula, and option C is ruled out as the IQ score is less than 100, indicating a lower mental age compared to the chronological age.
