Final answer:
Most students with emotional or behavioral disorders have IQs in the 'middle' or average range, which is between 85 and 115 according to the standard IQ bell curve.
Step-by-step explanation:
The question is asking for the typical IQ range of students with emotional or behavioral disorders. While these students can have varied IQ levels, including those that are gifted or have intellectual disabilities, the majority of them have IQs that fall within the average range. According to the standard bell curve of IQ, with the mean IQ score being 100 and one standard deviation being 15 points, most individuals, including those with emotional or behavioral disorders, typically have IQs between 85 and 115. This range is within one standard deviation above and below the mean and is considered average. Therefore, the correct answer to the question is, 'd. Middle.'
