My Doubts: Please explain why WHICH is wrong in [spoiler]A & E[/spoiler].

Also can IT in option C used as EXPLETIVE?

Many thanks in advance.

Meaning of the sentence: Production is expected to almost double and this would provide energy
In options A and E, usage of which illogically conveys the meaning that years would provide the energy.

In option C, it can be used as expletive

Forms of to be include is, was, has been, etc.
Generally, it may serve as an expletive only if it is followed by a FORM OF TO BE.
Official examples:
IT WAS only after Katharine Graham became publisher of The Washington Post in 1963 that it moved into the first rank of American newspapers.
IT WAS under her command that the paper won high praise.
IT IS unclear whether chimpanzees are unique among nonhuman species.

For a discussion of these examples, check my second post here:

C: production is expected that it will double
Here, it is followed by an action verb -- will double -- indicating that it is NOT serving as an expletive.
As a result, it seems to refer to production, conveying the following meaning:
production is expected that production will double.
This meaning is nonsensical.
Eliminate C.

Here, in this SC IT is not followed any one of these, so that's why IT is not used as Expletive right ?

To serve as an expletive, it must PRECEDE one of these clauses.

Correct.
