Why was divide and rule considered useful for colonial control?

Correct answer: It could weaken resistance by using local divisions

The direct answer is B: divide and rule could weaken resistance by using local divisions. Colonial rulers often faced opposition from people with different languages, religions, regions, classes or communities. If these groups were encouraged to distrust one another, they might fail to unite against foreign rule. The reasoning is: a united population can organize stronger resistance; deliberate emphasis on existing differences reduces trust and cooperation; divided groups find it harder to plan common action; colonial control therefore becomes easier. Option B is correct because it describes this political strategy. Option A is wrong because the policy aimed to weaken unity, not always strengthen it. Option C is wrong because divide and rule preserved control rather than immediately granting independence. Option D is wrong because it was a political and administrative strategy, not merely an economic reform. The word “could” is important: it describes a possible effect, not an automatic result everywhere. Memory cue: divide people, weaken common resistance, rule more easily.
