The correct answer is (d). Germany.
In 1864, the British government established the Indian Forest Service (IFS) with the help of German experts. The IFS was responsible for managing the forests of India, and it played a major role in the development of forestry in the country. The IFS was modeled on the Prussian Forest Service, and it adopted many of the Prussian forestry practices. These practices included scientific forestry, which is a system of forest management that is based on scientific principles. Scientific forestry emphasizes the need to protect forests from overexploitation, and it promotes the sustainable use of forest resources.
The IFS has been credited with helping to improve the management of forests in India. The IFS has also been involved in the development of new forestry technologies, and it has played a role in the conservation of forests. The IFS is still in operation today, and it is one of the most respected forestry organizations in the world.
The other options are incorrect because they are not countries that were involved in the establishment of the Indian Forest Service. France, Italy, and the United States did not have a significant role in the development of forestry in India.
