The correct answer is - C. Australia and the Pacific Islands.
The tropical wet and dry climate can be found in Australia and the Pacific Islands. To be more precise, this climate is found in the northern and northeastern part of Australia along the coastline, and in the Pacific it is only found in certain parts in some islands that are in its southern part. This climate is characterized by two seasons, wet season and dry season, which is why it has the mane wet and dry climate. During the wet period it has a very big amount of precipitation, and after that it has a few months long dry period when there's little to no rain. The temperatures are high throughout the whole year.
