What do you think?
Answered by thomas
my answer is b. but I don't know what is the elevation mean
Answered by Ms. Sue
B is right.

Elevation is the height or distance above sea level. The sub was at 35 feet below the level of the sea (-35). It then rose 35 feet so that it came to the surface at 0 feet above sea level.
