D. Semiarid. Humid subtropical and tropical wet are often associated with Southeast Asia, as there are versions of monsoon seasons that exist, bringing in large amounts of precipitation to the region.

The semiarid descriptor means an area with little precipitation per year, which does not exist in the region due to the significant amount of exposure to precipitation.
