Solution

The correct option is A 85
To find the mode of the given data, we first arrange the data into an ordered list of the marks and its frequency of occurrence:

Marks Frequency

87.5 1

Thus, from this, we can see that 85 is the most occurring value with a frequency of 3.

Hence, the mode of the given data set is 85.
