OA-not known
we should be clear when to use rather than and when to use instead of
1)instead of is used to show replacement of one thing over another.
Eg: I will have juice instead of milk. Here there is no preference of having milk only juice is required. Moreover instead of is always followed by a noun because instead of is a preposition.
2)Rather than is a conjunction and is used to show preference of one thing over another.
Eg: I will have juice rather than milk. Here is juice is not present I can have milk. Unlike instead of rather, since it is a conjunction, is followed by a noun, phrase, clause etc.
Now analyzing the sentences.
A: rather than burning calories to generate it (Correct, parallel to "by drawing their body". Just one questions to the experts if we add rather than by burning calories will it change the meaning?)
B: rather than the generation of body heat by burning calories (not parallel with "by drawing their body")
C: and not from generating it by burning calories (and is used but looking at the sentences an opposing indicator must be used not and)
D: instead of by burning calories for generating it (even though it looks parallel to "by drawing their body" , instead of requires a noun before it, but by burning calories doesn't help our cause)
E: instead of body heat generated by burning calories (changes the meaning : instead of body heat)
Hope this helps
