Answer:
The correct option is D. Tropical
Step-by-step explanation:
A tropical climate can be described as a climate present in regions where the average temperature remains more than 18 degrees Celsius (64 degrees Fahrenheit). Tropical climates do not usually have frost periods in them. However, precipitation is common in areas of the tropical climate. Hence, D is the correct option.
Other options like option A are not correct because events like fog or thunder are weather conditions. They are not climates.
