IMO D can be correct but it would have limitation. Consider the following scenario.
20 years ago say the cost of producing 1 unit of electricity by photovoltaic cells be $100 and let the present cost of producing the same electricity from fossil fuel be $12
So the present cost of producing electricity from photo cells is $10(follows from argument) and it is cheaper than that from fossil fuel ($12, our assumption)
But for D to be true, the cost of producing electricity from fossil fuels 20 yrs ago should be >$5
If it were say $4, then the cost of producing electricity from photo cells ($100 which is our assumption) will not be less than 20 times of $4 ($80) and any value less than $5 will have the same fate.
The question doesn't state the extent of increase of cost of producing electricity from fossil fuels.
I am new to this and so please correct me if am wrong
