The correct answer is - A. Cecil Rhodes and Leopold II traveled into the interior, showing other European leaders that such journeys were advantageous.
Rhodes and Leopold II in a way opened the gates for the European leaders to have the desire and go to the interior of the African continent. It was not just because of the possibility to do so because the African tribes were by far disadvantaged technologically and military compared to the Europeans, but it was the treasures that the continent was offering and how easy was it to get to them and use them for trade and become wealthy. That lead to a major colonization of the continent by the European colonial powers, and they took full advantage of the natural resources Africa had to offer.

The Sugar Act, also known as the American Revenue Act or the American Duties Act, was a revenue-raising act passed by the Parliament of Great Britain on 5 April 1764.[1] The preamble to the act stated: "it is expedient that new provisions and regulations should be established for improving the revenue of this Kingdom ... and ... it is just and necessary that a revenue should be raised ... for defraying the expenses of defending, protecting, and securing the same."[2] The earlier Molasses Act 1733, which had imposed a tax of six pence per gallon of molasses, had never been effectively collected due to colonial evasion. By reducing the rate by half and increasing measures to enforce the tax, the British hoped that the tax would actually be collected.[3] These incidents increased the colonists' concerns about the intent of the British Parliament and helped the growing movement that became the American Revolution.[4] ( THIS IS FROM WIKIPEDIA)
