(D) Step $1$: Identify the minimum and maximum values in the data.Minimum value $= 14$,Maximum value $= 112$.Step $2$: Determine the class size.The given class is $63-72$. Since $72$ is included,the class size is $72 - 63 + 1 = 10$.Step $3$: Form the classes starting from a value less than or equal to the minimum $(14)$.Starting from $3-12$ would be possible,but to cover $14$,we start from $3-12$ or $13-22$. Using $13-22$ as the first class:$13-22, 23-32, 33-42, 43-52, 53-62, 63-72, 73-82, 83-92, 93-102, 103-112$.Step $4$: Count the number of classes.There are $10$ classes in total.Therefore,the correct option is $D$.
