The correct answer is A. Provident Fund.
A provident fund is a savings account that is set up by an employer for their employees. The employee contributes a certain amount of money to the fund each month, and the employer may also contribute a portion. The money in the provident fund is invested, and the employee can withdraw it when they retire or leave the company.
A life insurance policy is a contract between an insurance company and an individual. The insurance company agrees to pay a sum of money to the beneficiary of the policy if the insured person dies. The individual pays a premium to the insurance company each month.
A national saving certificate is a type of government bond that is issued by the Reserve Bank of India. The certificate is a fixed-income instrument, and it pays a fixed rate of interest. The certificate can be purchased by individuals, and it is a popular investment option for people who are looking for a safe and secure investment.
A long-term government bond is a type of debt instrument that is issued by the government. The bond has a maturity of more than 10 years, and it pays a fixed rate of interest. The bond is a popular investment option for people who are looking for a safe and secure investment with a higher return than a savings account.
Of the above options, only provident fund is not viewed as a national debt. This is because provident fund is a savings account that is set up by an employer for their employees. The money in the provident fund is invested, and the employee can withdraw it when they retire or leave the company. On the other hand, life insurance policies, national saving certificates, and long-term government bonds are all types of debt instruments that are issued by the government.
