Final answer:
The cold weather season starts from November and lasts until February. The monsoon climate influences agricultural crops. Sudden rise in temperature in summer does not affect partially grown grains. Jet stream does not move air from high pressure to low pressure.
Step-by-step explanation:
Statement (a) is correct. The cold weather season typically starts from November and lasts until February. During this season, the land cools off and receives the northeast monsoon, which brings cooler temperatures and lower humidity.
Statement (b) is also correct. The monsoon climate in South Asia influences agricultural crops. The summer monsoon rains provide the water needed for agricultural production, and the winter monsoon winds bring moisture from the Bay of Bengal, which is important for crops.
Statement (c) is not correct. Sudden rise in temperature in summer does not affect partially grown grains. However, it can reduce the growing season of plants and increase the risk of low productivity, as warmer temperatures may not kill pests and may lead to damaging infestations in subsequent seasons.
Statement (d) is not correct. Jet stream is not moving air from high pressure to low pressure. Jet streams are fast-flowing, narrow air currents in the atmosphere, typically found at the tropopause. They are driven by the temperature and pressure differences between air masses.
