What is the usual term used to describe the climate of India?

Correct option is B

The correct answer is (b) Tropical monsoon.
 Tropical monsoon climate is the most common climatic classification for India.
 It is characterized by high temperatures, heavy rainfall during the monsoon season, and distinct wet and dry periods.
 The Indian Meteorological Department (IMD) has four official seasons:
 Winter: December to early April
 Summer or pre-monsoon: April to June, or April to July in northwest India
 Monsoon or rainy season: June to September
 Post-monsoon season: October to December.
Facts to remember:
 A polar climate is characterized by extremely cold temperatures and little precipitation, typical of regions near the Earth's poles such as Antarctica and the Arctic.
 A desert climate is characterized by extremely low rainfall, high temperatures during the day, and significant temperature fluctuations between day and night.
 An arid climate is similar to a desert climate, with extremely low rainfall and high temperatures.
 While parts of India, such as the Thar Desert, experience arid conditions, the term "arid climate" specifically refers to regions with very low precipitation levels, often less than 250 millimeters (10 inches) annually.
