What was the effect of linking Khilafat and Non-Cooperation on the movement?

Correct answer: The base of the movement became wider

The governing concept is the expansion of a mass national movement through the combination of related political concerns. Linking the Khilafat issue with the demand for swaraj brought many Muslim participants into a common anti-colonial campaign alongside other groups. Therefore option A is correct. The movement did not end, nor was it restricted to British people or soldiers; its social base became broader.
