We need to show that y = x/(x + c) is a solution of dy/dx = (y - y^2)/x. Then,
<span>dy/dx = ((x + c) * 1 - x * 1)/(x + c)^2 </span>
<span>= (x + c - x)/(x + c)^2 </span>
<span>= c/(x + c)^2 </span>
<span>and </span>
<span>(y - y^2)/x = (x/(x + c) - x^2/(x + c)^2)/x </span>
<span>= (x(x + c) - x^2)/(x(x + c)^2) </span>
<span>= (x^2 + cx - x^2)/(x(x + c)^2) </span>
<span>= cx/(x(x + c)^2) </span>
<span>= c/(x + c)^2 </span>
<span>which proves the equality. </span>

The correct answer is option C, that is, sustainable forestry.
A sustainable forestry refers to a forest, which is carefully administered so that as trees are cut, they are substituted with seedlings, which ultimately develop into mature trees. This is a skillfully and carefully managed system.
Sustainable forest management refers to the management of forests on the basis of the principles of sustainable development. Sustainable forest management has to maintain an equilibrium between the three prime pillars, that is, economic, ecological, and socio-cultural.
