Range of Data:
Range is a measure of dispersion that represents the difference between the highest and lowest values in a dataset. In this case, we need to find the range of the marks obtained by the 17 students in the mathematics test.

Given Data:
The marks obtained by the 17 students are as follows: 91, 82, 100, 100, 96, 65, 82, 76, 79, 90, 46, 64, 72, 68, 66, 48, 49.

Steps to Find the Range:
To find the range of the data, we need to follow these steps:

1. Arrange the data in ascending order:
46, 48, 49, 64, 65, 66, 68, 72, 76, 79, 82, 82, 90, 91, 96, 100, 100

2. Find the highest value:
The highest value in the data is 100.

3. Find the lowest value:
The lowest value in the data is 46.

4. Calculate the range:
Range = Highest Value - Lowest Value
= 100 - 46
= 54

Answer:
Therefore, the range of the data is 54 (option D).
