Explanation:

Here’s how it breaks down:

- Sardar Vallabhbhai Patel: Big leader, definitely a 'no-changer.' He wanted Congress to keep working inside councils rather than resorting to boycotts or disruptive tactics after the Non-Cooperation Movement ended.

- Dr. Ansari: Closely associated with the 'no-changers.' He favored continuing constructive work and Congress activity despite the setback.

- Babu Rajendra Prasad: Another strong supporter of the 'no-changer' approach. He was all about carrying on Gandhi’s constructive program.

- Motilal Nehru: Now, this is where things are different. Motilal Nehru led the 'Swarajists' or 'pro-changer' group. He pushed for Congress to enter legislative councils and fight from within, basically the opposite of the 'no-changers.'

So, Motilal Nehru was not a 'no-changer.' That’s your correct answer!
