The correct answer to this open question is the following.
What region do you suggest will be given priority in the vaccination program? Why?
Unfortunately, you do not specify if you are referring to the United States or the world.
If you are talking about the world, I would like to suggest that the region could be developing countries in Asia, Africa, India, or Latin America, because their citizens are poor and by the millions. So the spread of the disease could be more quickly and most of those countries do not have the kind of public health infrastructure to help their citizens. And this could affect the entire world.
If you are talking about the United States, then I would recommend vaccination for the larger urban areas and cities such as New York, Chicago, Houston, Dallas, or Los Angeles, because these are large cities overpopulated that have more risk to spread the disease due to the number of people that live and work there.

B and c is the answer to your question
The correct answer is: "integrity vs despair"
The question is refered to Erickson's steps of psychosocial development. This theory appoints that each stage in life poses a challenge. Two opposing forces act over the person, who has to be able to resolve the trade-off, by adopting the positive force (integrity, in this case) and discarding the negative one (despair), in order to sucessfully advance in the development of his/her psychosocial personality. The sucessful fulfilment of one step enables to reach the next step.
This period in a person's life, after 65 years old, means the beginning of the last stage of psychosocial development in which the person, for the first time, experiences a sense of mortality. Reaching integrity means accepting oneshelf and living in peace the way towards death, which is felt with proximity at this point in life.
