To find the change in height, we need to calculate the difference between the height from which Ping dove (10 meters) and the depth he reached in the water (6 meters).
The change in height is calculated as follows:
Change in height = Initial height - Final depth
Change in height = 10 meters - (-6 meters)
(The depth is below the water surface, so it's considered negative)
Change in height = 10 + 6 = 16 meters.
So, the correct response is:
16 meters
