Answer:C

Explanation:To answer this problem, we must identify what range is. Range is the difference between the smallest and largest numbers in a set of data. Remember it can be helpful to order your sets of numbers from least to greatest to help you, but it is not mandatory.

Lets take this information for the data sets provided.

For Set A: 100 – 10 = 90, so this won’t work.

For Set C: 50 – 10 = 40, this will work.

We know that set c works, so there is no need to move further.

The answer is letter c
