The red-cockaded woodpecker is an endangered species living in the southeastern U.S. Two of the primary factors that have contributed to the species' decline in numbers are:

1) Old pine trees required for nesting sites have been clearcut and logged by humans.

2) Humans have suppressed wildfires, which normally clear out other kinds of trees (hardwoods) from the understory. These hardwoods disrupt the woodpeckers' habitat and prevent new pines from growing.

How could humans manage fire as part of a multi-step plan to restore the stability of the red-cockaded woodpecker's ecosystem?
A.
Use controlled fires to clear out understory growth and help new pines grow.
B.
Use controlled fires to burn only the pine trees so the understory trees can grow.
C.
Use controlled fires to clear all the old pine trees and understory growth.
D.
Install irrigation systems to help prevent fires in the understory.
