This question is asking which suggestion would solve transportation problems associated with agriculture.

Option A suggests the establishment of tractor hiring units. Tractors can be used to transport agricultural produce and equipment, which can help in solving transportation problems.

Option B suggests an efficient railway system. A well-developed railway system can provide a cost-effective and efficient means of transporting large quantities of agricultural produce over long distances. This can help farmers in getting their products to markets and consumers more easily.

Option C suggests the establishment of car hire units. While car hire units can provide transportation services, they may not be the most suitable solution for addressing transportation problems associated with agriculture, as they may not be able to handle large quantities of produce or equipment efficiently.

Option D suggests the provision of extension services. Extension services are aimed at providing farmers with knowledge and information to improve their agricultural practices. While extension services can be beneficial in many aspects of agriculture, they may not directly address transportation problems.

Therefore, the correct option for solving transportation problems associated with agriculture is Option B: Efficient railway system. A well-developed railway system can provide a cost-effective and efficient means of transporting agricultural produce, helping farmers overcome transportation challenges.
