The correct answer is D. Sending military support to certain countries to fight the spread of Communism best displays the ideas stated in the Eisenhower Doctrine.

Explanation:

The Eisenhower Doctrine was the military doctrine of the United States from 1953 to 1962. This extremely rigid nuclear doctrine had a simple principle: any attack on a NATO member country by the USSR would expose it to massive nuclear reprisals, without notice and without restraint.  

Formulated at the beginning of the 1950s, the doctrine was framed within the context of the United States' superiority in nuclear weapons such that its use may appear to present a relatively limited risk for the United States, in view of the very significant potential destruction which would result in the USSR.

It also responded to Eisenhower's will for a strict orthodoxy in budgetary matters, in particular through a severe limitation of conventional armaments budgets made possible by the development, for a comparatively modest cost, of nuclear weapons.

the right choice would be a. culture within the city-state. c. loyalty to the police. d separation by land and sea.
