Answer:
C.
Step-by-step explanation:
In his inaugural speech, delivered on January 20, 1961, President John F. Kennedy used first person plural point of view to emphasis that we are all part of a global community and are therefore responsible for keeping peace and working toward ending poverty.
When Kennedy addresses that "we offer a special pledge ... in casting off the chains of poverty." He is including his audience as well insisting on that we all play an important role towards our global community and thus should work to maintain peace and combat poverty.
Therefore, option C is correct.
