(A) of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have Correct answer and no apparent errors.


(B) of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gasses having "having been" must be used to denote an action that has happened before another action. Incorrect usage here. Eliminate.


(C) of comparable size, and also they emit far fewer carbon dioxide and other gasses that have "and also" and "they" are redundant. Also, "far fewer carbon dioxide" is incorrect - need to use "lesser" for an uncountable. Eliminate.


(D) that have a comparable size, and also they emit far fewer of the other gasses having Omits to mention "carbon dioxide". "and also" and "they" are redundant. "having been" must be used to denote an action that has happened before another action. Incorrect usage here. Eliminate.


(E) that have a comparable size, as well as emitting far fewer of the other gasses having Omits to mention "carbon dioxide". Also, "having been" must be used to denote an action that has happened before another action. Incorrect usage here. Eliminate.
