Safety considerations aside, nuclear power plants are not economically feasible. While the cost of fuel for nuclear plants is significantly lower than the cost of conventional fuels, such as coal and oil, nuclear plants are far more expensive to build than are conventional power plants.
Which one of the following, if true, most strengthens the argument?
(A) Safety regulations can increase the costs of running both conventional and nuclear power plants.
(B) Conventional power plants spend more time out of service than do nuclear power plants.
(C) The average life expectancy of a nuclear power plant is shorter than that of a conventional one.
(D) Nuclear power plants cost less to build today than they cost to build when their technology was newly developed.
(E) As conventional fuels become scarcer their cost will increase dramatically, which will increase the cost of running a conventional power plant.

Life expectancy shorter , means even if it is economically feasible , will result in increased cost by building plant again and again

Premise1: nuclear power plants are not economically feasible
Premise2: while the cost of fuel for nuclear plants is significantly lower than the cost of conventional fuels, nuclear plants are far more expensive to build than are conventional power plants.
With prethinking, I need to figure out why with the cost of fuel is lower, nuclear plants are still far more expensive than conventional power. There will be another factor leading to that result.
(A) Safety regulations can increase the costs of running both conventional and nuclear power plants.
As it was mentioned, "Safety considerations aside", so this is out of scope.
(B) Conventional power plants spend more time out of service than do nuclear power plants.
we do not mention anything about spending time. so this is out of scope.
(C) The average life expectancy of a nuclear power plant is shorter than that of a conventional one.
this one could be the answer since the average life expectancy of a nuclear power plant is shorter, we need to spend more in order to renew or expend its life expectancy.
(D) Nuclear power plants cost less to build today than they cost to build when their technology was newly developed.
this weakens the argument actually.
(E) As conventional fuels become scarcer their cost will increase dramatically, which will increase the cost of running a conventional power plant.
this also weakens the argument.
