On an aircraft with an all-moving tailplane, pitch up is caused by
- decreasing tailplane incidence.
- forward movement of the control column.
- increasing tailplane incidence.
Explanation from PART66Online
On an all-moving tailplane, reducing the tailplane incidence makes the tail carry a greater download, or a smaller upload, which pushes the tail down and pitches the nose up. Increasing the incidence does the opposite and gives a nose-down pitch, and moving the control column forward is the input that commands that nose-down pitch, so neither of those produces pitch up.

How else would the nose come up if the tail isn't pushing down harder? It's A, decreasing the tailplane incidence loads the tail down more, so the tail drops and the nose pitches up. Heads up though, the other two options are basically saying the same thing, raising and increasing the incidence, so one of them looks like a typo.
