Concept:Both statements are factually correct, but the second does not explain the first because the Akali upsurge was a separate religious reform movement, not the cause of the student-led non‑cooperation in Punjab.
Explanation:The Non‑cooperation Movement began in Punjab with a student walk‑out in Lahore in January 1921, inspired by Lala Lajpat Rai.
Hence Statement I is true.
The Sikh‑dominated central Punjab countryside was indeed stirred by the powerful Akali upsurge (a movement for control of gurdwaras).
Hence Statement II is also true.
However, the student movement was part of the national non‑cooperation campaign, while the Akali movement was a local religious reform struggle.
Statement II does not provide the reason why the student movement started; the two events occurred around the same time but were not causally linked.
Therefore, both statements are individually true, but Statement II is not the correct explanation of Statement I.
Answer:Option B: Both statements are individually true but Statement II is not the correct explanation of Statement I.
