The correct answer is: d) All of the above.
Fog is a common occurrence in Meghalaya during all seasons. The state has a humid subtropical climate with heavy rainfall throughout the year. The average annual rainfall in Meghalaya is over 12,000 mm. The high humidity and rainfall create ideal conditions for fog to form.
Fog is most common during the monsoon season, which runs from June to September. During this time, the state receives the majority of its annual rainfall. The heavy rainfall and high humidity create thick fog that can reduce visibility to a few meters.
Fog can also occur during the winter months, when the temperature drops and the air becomes more stable. The cold air can trap moisture in the air, creating fog. Fog is less common during the summer months, but it can still occur on some days.
The fog in Meghalaya can be a nuisance, as it can reduce visibility and make driving dangerous. However, the fog also has a certain beauty, and it can be a popular tourist attraction.
