Forest fires can be a problem in Manipur, especially during:

The dry season
The monsoon season
The winter season
All of the above

Forest fires can be a problem in Manipur, especially during the dry season. The dry season is from November to April, and during this time, there is little rainfall. This makes the forests very dry and susceptible to fire. The dry season is also the time of year when people are most likely to be burning wood for cooking and heating. This can also contribute to forest fires.

The monsoon season is from June to September, and during this time, there is a lot of rainfall. This makes the forests less susceptible to fire. However, if there is a lightning strike during the monsoon season, it can cause a forest fire.

The winter season is from October to December, and during this time, there is some rainfall. However, the forests are still dry enough to be susceptible to fire. If there is a dry spell during the winter season, it can increase the risk of forest fires.

Therefore, the correct answer is: The dry season.

The monsoon season and the winter season can also be problematic, but the dry season is the most dangerous time for forest fires in Manipur.
