Explanation:

Central co-operative banks are a crucial part of the co-operative banking system in India. They play a significant role in providing credit and financial services to the rural and agricultural sectors. These banks are in direct touch with various stakeholders, including farmers, state co-operative banks, land development banks, and the central government. However, the correct answer is option B, which states that central co-operative banks are in direct touch with state co-operative banks. Let's understand why this is the correct answer in detail.

Role of Central Co-operative Banks:
Central co-operative banks act as a bridge between the primary agricultural credit societies (PACS) and state co-operative banks. They are responsible for mobilizing funds from the state co-operative banks and providing financial assistance to the PACS. These banks directly interact with and cater to the needs of the primary agricultural credit societies, which primarily consist of farmers.

Relationship with State Co-operative Banks:
State co-operative banks serve as the apex financial institutions at the state level in the co-operative banking system. They provide financial support and resources to the central co-operative banks. The central co-operative banks act as their intermediary and channelize the funds received from the state co-operative banks towards the primary agricultural credit societies.

Importance of Direct Touch:
The direct touch between central co-operative banks and state co-operative banks is critical for effective coordination and financial flow within the co-operative banking system. It ensures the smooth transfer of funds, enables efficient credit delivery to the farmers, and facilitates the implementation of various agricultural and rural development schemes.

Other Stakeholders:
While central co-operative banks do have interactions with other stakeholders like farmers, land development banks, and the central government, these interactions are not as direct or significant as their relationship with state co-operative banks. Farmers, for instance, primarily access credit and financial services through the primary agricultural credit societies, which are directly linked to central co-operative banks.

Conclusion:
In conclusion, central co-operative banks are in direct touch with state co-operative banks. This relationship is crucial for the functioning of the co-operative banking system and ensures effective credit delivery to farmers and rural development. While central co-operative banks do interact with other stakeholders, their primary role is to facilitate the flow of funds from state co-operative banks to the primary agricultural credit societies.
