The correct answer is A. Social security payments.
Social security is termed as system of government which provides monetary assistance to all the people who have no income or their income is inadequate.
There are some traditional contingencies which social security covers. For example, maintenance of children responsibility, morbid condition treatment, inability which is permanent or persistent to be involved in gaining activity, and losses and costs which are being involved in medical care.
Social security can either be service, insurance, or basic security.
