The mode of given data set is 74. Option D is correct option.

Step-by-step explanation:

We need to find mode of the data set

The data according to key is: 5|0 = 50 years old

So, data will be:

50,54,56,60,62,63,64,68,68,69,70,72,73,74,74,74,78,79,84,85,86,88

Mode is the most repetitive value in the data set.

So, the most repetitive value is 74.

The mode of given data set is 74. Option D is correct option.
