Answer:
B. They had no representation in Parliament.
Explanation:
After the French and Indian War, the British Crown increased taxes to pay the enormous debts it had incurred in to win the war with France. This caused much discontent among American colonists; one common complaint of this time was "taxation without representation." The colonists felt they were carrying a too heavy burden without having the right to choose their representatives in the British Parliament or sending envoys. This is a factor leading to the Revolutionary War.
Nigeria had much division between tribal/ethnic groups vying with one another for power, and thus were not working together for a united purpose. Nigeria's wealth of natural resources also gave them much to be fighting over as the groups each sought advantage.
Botswana, on the other hand, was one of the poorest countries in the world when it gained its independence from Britain in 1966, and it avoided infighting and political corruption like that seen in Nigeria. They have been a multi-party democracy since that time -- the longest-running multi-party democracy on the African continent. Botswana enjoyed significant economic growth also as it worked together politically.
