Why did the central leadership decide to postpone carving out states based on language?

All of the above

After its Nagpur session in 1920, Congress recognized the linguistic principle for reorganising its party committees.
However, after Independence and partition, there were concerns that creating states solely based on language could disrupt and detract from other pressing social and economic issues.
The central leadership decided to postpone the matter of linguistic reorganization and focus on social and economic challenges.
This decision was influenced by the unresolved fate of the Princely States and the recent memory of partition. They wanted to avoid anything that may lead to disintegration and disruption of the country.
Postponement allowed for a comprehensive and careful approach to address the linguistic and cultural diversity of the country while ensuring its unity and stability.
