Answer:
B. Rebels.
Step-by-step explanation:
Decolonization is the process by which a colonized state or nation rebels against the imperial power under whose power the colony is. This will include revolts or any form of dissatisfaction or anger against the power ruling it.
In this case, decolonization movements will aim to free the nation from the governing foreign authority. And those leaders who organize or lead such movements will be seen as rebels, terrorists, dissenters, oppositions, etc. With the aim to overthrow the power ruling them, and desiring to free the people from such ruling hands will make them 'enemies' of the imperial country. They will be seen as 'rebels', rebelling against the authority, the government, the power ruling them.
Thus, the correct answer is option B.
