The correct option is Akali Dal.

Step-by-step Explanation:

1. Understanding the Punjabi Suba Movement:
The Punjabi Suba movement was a long-drawn political agitation launched in post-independence India (specifically starting in the late 1940s and continuing through the mid-1960s). The primary objective of the movement was the creation of a state (Suba) where Punjabi-speaking people would form the majority, carved out of the then bilingual state of East Punjab (which included Punjabi and Hindi speaking regions).

2. Role of the Akali Dal:
The movement was spearheaded and led by the Shiromani Akali Dal, a premier Sikh political party. Prominent leaders of the Akali Dal, such as Master Tara Singh and later Sant Fateh Singh, played pivotal roles in mobilizing public support, organizing peaceful protests (morchas), and negotiating with the central government of India.

3. Outcome:
Due to the intense movement and persistent demands led by the Akali Dal, the Government of India eventually agreed to reorganize the state. Under the Punjab Reorganisation Act of 1966, the bilingual state of Punjab was divided, leading to the formation of a new Punjabi-majority state of Punjab, while the Hindi-speaking areas were split to form the new state of Haryana and some territories were transferred to Himachal Pradesh.
