`\begin{gathered} Option\text{ A} \\ From\text{ the graph} \\ Class\text{ A range = }85-70 \\ Class\text{ A range = 15} \\ Class\text{ B range = }93-72 \\ Class\text{ B range = }21 \\ Class\text{ A range<}Class\text{ B range, hence this option is false.} \\ \\ \text{Option B} \\ From\text{ the graph} \\ \text{Median score }class\text{ A=}77 \\ \text{Median score }class\text{ B=}80 \\ \text{Median score }class\text{ B-Median score }class\text{ A}=80-77 \\ \text{Median score }class\text{ B-Median score }class\text{ A}=3\text{, therefore } \\ \text{this option is TRUE} \\ \\ Option\text{ C} \\ IQR\text{ }Class\text{ A = }82-73 \\ IQR\text{ }Class\text{ A = 9} \\ IQR\text{ }Class\text{ B = }87-73 \\ IQR\text{ }Class\text{ B = 14} \\ So\text{ this option is false.} \\ \\ Option\text{ D} \\ \text{The statement of the option D can not be demonstrated} \\ \\ \text{For all, the only statement that is true is option B} \end{gathered}`
