A
stabilising selection.
B
directional selection.
C
disruptive selection.
D
random selection.

Solution:

Natural selection can lead to stabilisation if more individuals acquire mean character value. In this case, average sized pine trees are surviving and both the extreme traits(short and tall) are being eliminated. So, it is a stabilising selection.
