Correct Answer: Option A
A. The crisis of modernization of the 20th Century
Explanation
The crisis of modernization of the 20th century is the correct answer. Islamic reform movements developed majorly in response to the challenges of social development (e.g. the Mosques are often known as platforms for criticism of the shortcomings of the African government regimes), educational reform (e.g. training as religious scholars), and the popularisation of Islamic values.
