The correct answer is D. War on poverty, Medicaid, Medicare and national endowment for the humanities were part of the "Great Society" programs during the administration of Lyndon B. Johnson.
Explanation:
The Great Society was a large-scale social reform program of the US government under the presidency of Lyndon B. Johnson. The program was proclaimed in early 1964, a few months after Johnson took over as President after the assassination of his predecessor, John F. Kennedy, and continued until January, 1969. The main objectives of the reform program were the fight against poverty, the strengthening of the rights of African Americans and other minorities, as well as comprehensive reforms in the field of education and health. Other aspects included environmental and consumer protection and the expansion of infrastructure.
