A scheme aimed at providing credit and financial assistance to farmers in Arunachal Pradesh is the:

Kisan Credit Card Scheme
Deen Dayal Upadhyaya Grameen Kaushalya Yojana
Pradhan Mantri Awas Yojana
Atal Pension Yojana

The correct answer is (a) Kisan Credit Card Scheme.

The Kisan Credit Card Scheme is a credit scheme for farmers in India. It was launched in 1998 by the Government of India. The scheme provides loans to farmers for agricultural purposes, such as buying seeds, fertilizers, and pesticides. The loans are provided at a low interest rate and are repayable over a period of 3 to 5 years.

The scheme has been successful in providing financial assistance to farmers. As of 2017, the scheme had disbursed loans worth over ₹1 lakh crore to over 10 crore farmers. The scheme has also helped to increase agricultural production and productivity.

The other options are incorrect because they are not schemes aimed at providing credit and financial assistance to farmers in Arunachal Pradesh.

(b) Deen Dayal Upadhyaya Grameen Kaushalya Yojana is a scheme aimed at providing skill training to rural youth.

(c) Pradhan Mantri Awas Yojana is a scheme aimed at providing housing assistance to the poor.
