In this set, the incorrect pair is Azadi Movement - West Bengal. The Azadi Movement, also known as the Indian independence movement, was a pan-Indian struggle for independence from British colonial rule and was not specific to West Bengal. It was a nationwide movement that involved various regions, leaders, and ideologies.
Step 1: The Azadi Movement is not linked to any specific state, it was a national struggle led by figures like Mahatma Gandhi, Jawaharlal Nehru, and others.
Step 2: The other pairs, Panchayati Raj - 73rd Amendment and IAS - All India Services, are correct because Panchayati Raj refers to a system introduced by the 73rd Constitutional Amendment, and the IAS (Indian Administrative Service) is indeed part of the All India Services.
Step 3: The correct pair for the Azadi Movement should be Indian Independence Movement instead of West Bengal.
Final Answer:
\[
\boxed{(B) \, \text{Azadi Movement - Indian Independence Movement}}
\]
