While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.

A. While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.
B While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive.
C. Even though it costs about the same to run nuclear plants as for other types of power plants, it is the fixed costs that stem from building nuclear plants that makes the electricity they generate more expensive.
D. It costs about the same to run nuclear plants as for other types of power plants, whereas the electricity they generate is more expensive, stemming from the fixed costs of building nuclear plants.
E. The cost of running nuclear plants is about the same as other types of power plants, but the electricity they generate is made more expensive because of the fixed costs stemming from building nuclear plants.

A and C are out because of subject verb agreement. D has a dangling modifier and E seems just awkward. what if another option is here such as F

F The cost of running nuclear plants is about the same as for other types of power plants, but the electricity they generate is more expensive because of the fixed costs stemming from building nuclear plants. is there any grammatical and meaning error.

Hi nafiul9090,

F would not be a good sentence because the pronoun "they", while trying to refer to "nuclear plants", is close to "other types of power plants".

In GMAT, dont we use "while" to show two simultaneous actions and not for comparison? That is why I ruled out all the "while" options. Although no other option looks better than B but how can we use while for comparisons.

Experts please help.

Thanks
