c. gradually starves the stem
d. all of the above

Explanation:

In air layering, girdling (cutting bark) is done to stimulate root formation at the wounded site. Option a is incorrect as girdling isn't for breaking the stem later. Option c is incorrect as the goal isn't to starve the stem. So the correct reason is stimulating root formation at the wound.

b. stimulates root formation where the plant has been wounded
