Inner core, outer core, mantle and crust
Answer: B) because in higher plants, such as angiosperms and gymnosperms, the sporophyte is the dominant generation.
Explanation:
Gravitational potential energy = mgh, where m is the mass of the mountain climber, g is the gravitational force and h is the height from the base.
Since m and g are constants, the climber's potential energy will be the lowest when he's at the end of the climb, at the base of the mountain. (B)
