What popular nickname is used for Jayaprakash Narayan, the Indian freedom fighter and political leader associated with the Total Revolution movement?

Introduction / Context:
Jayaprakash Narayan was a prominent Indian freedom fighter and later a key figure in opposing authoritarian tendencies in Indian politics during the 1970s. He is popularly known by a special title that reflects his status as a leader of the people. This question tests whether you can correctly recall that nickname from among several similar sounding terms.

Given Data / Assumptions:

• The question is specifically about the nickname of Jayaprakash Narayan.
• Options include Lok Pal, Lok Nayak, Lokansh, Lok Satta and Jan Nayak.
• We assume general awareness of modern Indian political history and Emergency period events.

Concept / Approach:
The key concept is that Jayaprakash Narayan is widely called Lok Nayak, which literally means People's Leader. This title was given because of his moral authority and the leadership he provided to mass movements, especially the Total Revolution campaign against the Emergency. The other terms in the options either refer to institutions or are distractors deliberately shaped to confuse the memory.

Step-by-Step Solution:
Step 1: Recall that Jayaprakash Narayan played a critical role in mobilising people during the movement against the Emergency.Step 2: Remember that he is often referred to as Lok Nayak in biographies, documentaries and textbooks.Step 3: Examine the options and note that Lok Pal is usually the name of an anti corruption ombudsman, not a personal nickname.Step 4: Lokansh and Lok Satta do not correspond to standard historical titles for Jayaprakash Narayan.Step 5: Jan Nayak is a generic term meaning People's Leader, sometimes used informally for other leaders, but the recognised title for Jayaprakash Narayan is Lok Nayak.Step 6: Select Lok Nayak as the correct answer.

Verification / Alternative check:

Why Other Options Are Wrong:
Lok Pal is wrong because it refers to an office created to look into public grievances and corruption cases, not to Jayaprakash Narayan himself.Lokansh is not a standard term linked to any major leader in common exam material.Lok Satta refers to a political party and is not the title of Jayaprakash Narayan.Jan Nayak is a meaningful phrase but not the specific, widely used honorific associated with him; exams expect Lok Nayak.

Common Pitfalls:
Because several options contain the word Lok, some candidates get confused and pick Lok Pal or Lok Satta by mistake. Others rely only on the word Nayak and may choose Jan Nayak. To avoid this, memorise the exact phrase Lok Nayak Jayaprakash Narayan as it appears in multiple contexts, such as the Delhi Metro station named after him.

Final Answer:
The correct answer is Lok Nayak.
