A. Many people moved from rural areas to urban centers,

Explanation:

During the late 1800s the flow of people from rural areas to urban was maximum. At this age there were lots of big industries being built and run during industrialisation phase so people went to urban areas for the jobs.

As the large portion of population couldn’t depend upon the agriculture in rural areas hence they migrated to the cities seeking the jobs and opportunities.  

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
