The correct answer is: B. 10th June
The monsoon winds arrive in Eastern Bihar around 10th June. The monsoon is a seasonal wind that blows from the southwest to the northeast across the Indian subcontinent. It is caused by the difference in temperature between the land and the ocean. The land heats up faster than the ocean, and this creates an area of low pressure over the land. The high pressure over the ocean then pushes the monsoon winds towards the land.
The monsoon winds bring heavy rains to Eastern Bihar. The rains are essential for the region’s agriculture. The monsoon also helps to replenish the groundwater and prevent droughts.
The monsoon winds usually arrive in Eastern Bihar around 10th June. However, the exact date can vary from year to year. The monsoon winds can arrive as early as 1st June or as late as 15th June.
The monsoon winds are a vital part of the climate of Eastern Bihar. They bring much-needed rain to the region and help to support the local agriculture. The monsoon winds also play an important role in the region’s culture and economy.
