In order to answer you question I need more details on what you're asking!
I am not an expert on this but i know that with the industrial era, brought a even higher demand on cotton. They were making more faster.
So i would go with B because they needed more slaves to keep up with demand.
Answer:
Yes , I agree.
European countries became the most powerful countries among the other countries through conquest and trade especially in spices and also in textile.
India's land perfectly suits to grow spices and cotton while the conditions in European countries were not suitable.
As their countries were not suitable to grow the raw material for their industries European countries started colonising different countries.
Whenever Vasco Da Gama found the sea route to India the arrival of different European countries started.
However the search of wealth and prosperity by India also made it to be colonised by European countries.
Not my own answer.... It's from Google but hope helps you.
