Please explain with reasons....

Columnist: The relief from the drudgery of physical
labor that much modern technology affords its
users renders them dependent on this technology,
and, more importantly, on the elaborate energy
systems required to run it. This leads to a loss of
self-sufficiency. Clearly, then, in addition to
undermining life's charm, much modern technology
diminishes the overall well-being of its users.
Which one of the following is an assumption required
by the columnist's argument?
(A) Physical labor is essential to a fulfilling life.
(B) Self-sufficiency contributes to a person's well-being.
(C) People are not free if they must depend on
anything other than their own capacities.
(D) Anything causing a loss in life's charm is
unjustifiable unless this loss is compensated by
some gain.
(E) Technology inherently limits the well-being of
its users.
