Fanleaf virus is also known as which term?

Explanation:
Fanleaf degeneration describes the disease syndrome caused by grapevine fanleaf virus. The virus is named Grapevine fanleaf virus, and the disease it produces in grapevines is commonly called grapevine fanleaf degeneration (often shortened to fanleaf degeneration). This naming reflects how the pathogen and the disease are linked: the virus causes a recognizable set of symptoms that leads to degeneration of vine vigor and yield. The other options don’t fit because they either aren’t the standard disease name (grapevine degeneration, grape degeneration) or use the wrong genus (Vitus degeneration; the correct genus is Vitis).
