Explanations:The question asks about the need for woolen clothes, which is primarily determined by the climate and elevation of a region. Woolen clothes are typically required in areas with cold climates, particularly during the winter months. The state of Himachal Pradesh, located in the northern part of India, is characterized by its high altitude and cold climate, especially in the winter season. This makes it necessary for the residents and visitors to wear woolen clothes to stay warm and protected from the cold.
Let's examine the other options in detail:
Goa, located on the western coast of India, has a tropical climate with warm temperatures throughout the year. The average temperature in Goa ranges from 20°C to 35°C, making it unnecessary to wear woolen clothes. The climate is influenced by the proximity to the Arabian Sea, which moderates the temperature and keeps it relatively warm even during the cooler months.
Tamil Nadu, situated in the southern part of India, also has a tropical climate. The state experiences hot and humid weather, with temperatures rarely dropping below 20°C. The climate is influenced by the Bay of Bengal and the Arabian Sea, which contribute to the warm and humid conditions. Therefore, woolen clothes are not typically needed in Tamil Nadu.
Kerala, another southern state, shares similar climatic conditions with Tamil Nadu. It has a tropical climate with high humidity and warm temperatures. The state is known for its lush greenery and heavy rainfall, particularly during the monsoon season. The average temperature in Kerala ranges from 20°C to 35°C, making woolen clothes unnecessary.
In contrast, Himachal Pradesh, located in the northern part of India, is a mountainous state with a cold climate. The state is known for its high altitude and the presence of the Himalayan mountain range. The temperature in Himachal Pradesh can drop significantly during the winter months, with temperatures often falling below 0°C in some areas. The cold climate necessitates the use of woolen clothes to provide warmth and protection against the cold.
Therefore, the correct answer is Himachal Pradesh, as it is the only state among the given options that requires woolen clothes due to its cold climate and high altitude.
