Industrialization encouraged empire building because a nation’s need for products to sell to citizens could be met. a nation’s need exceeded the kind of raw materials the nation had. the nation needed the expertise of the colonists. the nation needed the workforce that colonists could provide.

The correct answer is a nation’s need exceeded the kind of raw materials the nation had.

Imperialism partially arose from the need to obtain vaster supplies and raw materials for the different European economies. Hence, imperialism developed, in some aspects, as a direct effect of the industrial revolutions that were taking place over Europe through the nineteenth century.  

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.
