The correct answer is option-1 AW. The Tropical Savannah climate, also known as the Aw climate, is characterized by distinct wet and dry seasons. It is typically found in regions closer to the equator, where there is a consistent high temperature throughout the year.

Now let`s dissect the other options to understand why they are not indicators of the Tropical Savannah climate:

Option-2 Dfc represents the Subarctic climate, which is characterized by extremely cold winters and short, cool summers. This climate is typically found in high-latitude regions.

Option-3 Cwg represents the Warm Maritime climate. This climate is characterized by mild winters and cool summers, often accompanied by high precipitation. It is commonly found in coastal areas.

Option-4 Am represents the Tropical Monsoon climate. This climate is characterized by high temperatures and heavy rainfall during one season, followed by a drier season. It is commonly found in areas near the Indian Ocean and the Pacific Ocean.

Therefore, the Tropical Savannah climate is best represented by option-1 AW.
