The correct answer is: Monsoon season.
The monsoon season is the wettest time of year in Manipur, and it is during this time that waterlogging is most likely to occur. The monsoon season typically runs from June to September, and during this time, heavy rains can cause rivers to overflow their banks and flood low-lying areas. This can lead to a number of problems, including damage to property, disruption of transportation, and health problems.
The winter season is the driest time of year in Manipur, and it is during this time that waterlogging is least likely to occur. However, even during the winter, there can be periods of heavy rain, which can lead to waterlogging in some areas.
The dry season is the second-driest time of year in Manipur, and it is during this time that waterlogging is less likely to occur than during the monsoon season, but more likely to occur than during the winter season.
Waterlogging can occur throughout the year in Manipur, but it is most common during the monsoon season.
