At which point is her kinetic energy increasing and her
potential energy decreasing?

kinetic energy increases a s something is moving, and potential decreases a something is moving, and increases as something goes to its highest point.

Explanation:

potential energy is built up or stored energy, so as soon as something starts moving the energy begins to decrease. Kinetic is the opposite, and builds with movement.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
