The correct option is B Indonesia
The Dutch capitalists started investing in Indonesia to set up plantations in which a single crop like rubber, pepper or sugarcane was extensively planted. These were managed by the Dutch planters. Many of the crops were even brought from distant countries like India. Thus, the Dutch Indonesia produced most of the worlds supply of quinine and pepper, over a third of its rubber, a quarter of its coconut products, and a fifth of its tea, sugar, coffee, and oil.
