To determine which landform corresponds to the number 5 on the map, I would need to see the map in question, which I currently cannot do. However, I can provide you with information about each option, and you may identify the correct landform based on its characteristics or location.
A. Korean Peninsula - Located between the Yellow Sea and the Sea of Japan, it includes North and South Korea.
B. Honshu - The largest island of Japan, home to cities like Tokyo and Kyoto.
C. Gobi Desert - A vast desert located in northern China and southern Mongolia.
D. Malay Peninsula - A peninsula in Southeast Asia that includes parts of Malaysia and Thailand, running south towards Singapore.
If you can provide more context regarding the map or the location in question, I'd be happy to assist further!
