Dairy farming with cattle is primarily practiced in:

The correct answer is: d) Coastal plains.

Dairy farming is the process of raising cattle for milk. It is a major agricultural industry in many parts of the world. The best places for dairy farming are areas with a temperate climate, plenty of water, and good grazing land. Coastal plains are ideal for dairy farming because they have all of these features.

High altitude regions are not suitable for dairy farming because the climate is too cold and the air is too thin. Urban centers are not suitable for dairy farming because there is not enough space for grazing land. Forested areas are not suitable for dairy farming because the trees shade the ground and make it difficult for grass to grow.

Here are some additional details about each option:

• High altitude regions are typically cold and have thin air. This makes it difficult for cattle to grow and produce milk.
• Urban centers are typically crowded and have little space for grazing land. This makes it difficult to raise cattle.
• Forested areas are typically shaded by trees. This makes it difficult for grass to grow, which cattle need to eat.
• Coastal plains are typically flat and have a temperate climate. This makes them ideal for grazing land and raising cattle.
