Which one of the following is not correct regarding South India?

A) Diurnal range of temperature is low
B) Annual range of temperature is less
C) Temperature is high throughout the year
D) Extreme climatic conditions are found

South India is characterized by a tropical maritime climate due to its proximity to the equator and the influence of the surrounding Arabian Sea, Bay of Bengal, and Indian Ocean [2]. Unlike North India, which lies in the sub-tropical zone and experiences extreme climatic conditions with high daily and annual temperature ranges, South India falls within the tropical zone [3]. This location ensures that temperatures remain high throughout the year, typically above 18°C even in the coldest months [3]. The maritime influence results in a moderate climate with a small diurnal range of temperature (around 5°C–6°C in coastal areas) and a low annual range of temperature [3]. Therefore, the statement that 'extreme climatic conditions are found' in South India is incorrect, as such extremes are characteristic of the continental climate found north of the Tropic of Cancer [3].
