The correct answer is: Month.
Monsoon is a seasonal rain that occurs in tropical and subtropical regions. It is caused by the difference in temperature between the land and the ocean. The land heats up faster than the ocean, which causes the air above the land to rise. This rising air creates an area of low pressure, which draws in moist air from the ocean. This moist air rises and cools, condensing into clouds and rain.
April is the fourth month of the year in the Gregorian calendar, coming between March and May. It is the second of seven months to have a length of 30 days. April was named after the Latin word aperire, meaning “to open”, because it is the month when plants begin to bloom.
