Correct option is C
Lucian Pye, a political scientist known for his work on political development, described various crises that countries face as they develop. Among the options provided, the crises identified by Pye include:
(A) Identity crisis, which concerns the challenge of developing a national identity.
(B) Legitimacy crisis, which involves the struggle for the government to be recognized as right and proper by its people.
(C) Penetration crisis, referring to the state's ability to implement policies and assert control throughout its territory.
While welfare issues are certainly critical in political development, the specific term "Welfare crisis" is not one of the crises Pye explicitly described in his framework. Therefore, the most appropriate answer is (c) A, B, and C only.
