What was one deeper reason for the slowing down of the Non-Cooperation Movement in urban areas?

Correct answer: Khadi and alternative institutions were not easily available to everyone

The urban programme depended on practical alternatives to government schools, colleges, courts and foreign cloth. Although students, teachers, lawyers and merchants participated, national educational institutions were limited and khadi was often more expensive than mill-made cloth. Sustaining a boycott therefore became difficult for many people. Hence option A is correct. The other options are incorrect: the government did not permanently ban foreign cloth, students did not reject national education completely, and Congress did not simply stop working in towns.
