Explanation:

A. Lets convert millimeters into kilometers.


1cm = 10mm \\ 10mm = 1cm \\ 10 * 30 = 1 * 30 \\ 300mm = 30cm \\ 30cm > 3cm

since 4000000mm = 4km, A is true. (Not the answer)

B. Lets convert millimeters into centimeters.


1cm = 10mm \\ 10mm = 1cm \\ 10 * 30 = 1 * 30 \\ 300mm = 30cm \\ 30cm > 3cm

Since 300mm > 3cm, B is true. (Not the answer)

C. Lets convert millimeters to meters.


1000mm = 1m \\ 1m = 1000mm \\ 1 * 5 = 1000 * 5 \\ 5m = 5000mm

Since 5m = 5000mm, C is NOT true. (Answer)

D.Lets convert metres to kilometres.


1km = 1000m \\ 1 * 2 = 1000 * 2 \\ 2km = 2000m \\ 2km < 20km

Since 2000m < 20km, D is true. (Not the Answer.)
