Explanation

The range of 200 measurements = 17 cms

If 49.5 is the lowest measurement in the set

The highest measurement in the set of measurement = 49.5 + range = 49.5 + 17 = 66.5 cms

If 49.5 is the highest measurement in the set

The lowest measurement in the set of measurement = 49.5 - range = 49.5 - 17 = 32.5 cms.

In the second case we have two values that lie between 32.5 cms and 49.5 cms.

Thus option is C and D is correct.

As the range between the measurement is given as 17, it means the highest and lowest measurement has difference between 17.
As it a could be question, we can take all possible answer into consideration, if the difference between the number is less than 17.
so the answer is C and D. since 49.5- C < 49.5 - D < 17.
