Should the writer keep or delete the bold text?

a
Keep it, because it is an essential component of the writer's argument that his son should share what he has learned with others.

b
Keep it, because it emphasizes the advantages gained and thereby the guilt the son should feel for not valuing his education.

c
Keep it, because it emphasizes the notion that the recipient of the letter should know better due to his advanced age.

d
Delete it, because it clutters an already lengthy sentence with unnecessary wordiness and provides no additional commentary.

e
Delete it, because it refutes early claims made by the writer with regard to the nature of his son's opportunities in life.
