IMO D. Narrowed down to C and D.
lets consider a scenario:
20 years back Photovoltaic power plants costs 100, so today they cost 10
Now, for Photovoltaic power plants to be less expensive traditional plants today must cost less than 10.
Tradtional plants:
20 years back costs 1 then today might 10. Incase of former conclusion fails and in case of latter conclusion holds valid.
Thus, We need some detail which validates it is >10 to hold conclusion valid. D provides this info. When 20 years back it was lower than traditional plants costs, it must be less expensive now as well. Hence D.

IMO D.
First ask yourself what forced the central bank to intervene? Is it 'currency continued its slide to a record low' (subject of the preceeding phrase) or 'dollar' (object of the preceeding phrase). It the former one, convinced till here? Ok!!
Now the difference between forcing and which forced:
A participle phrase set-off by a comma always modify the subject of the preceeding phrase whereas a phrase introduced by relative pronoun which modifies the immediate previous noun. So in this item, 'forcing' modifies 'currency continued its slide to a record low' and 'which forced' modifies 'dollar'.
Hence D.
but abhasjha u remember i posted a question few days back where who was referring to tribe and not the people. Let me search and post the question again.
1. we need a conjuction "and" to join to phrases. D and E are out.
2. both superioty over and superioty to are correct in GMATLand.
3. simple past tense is used in first phrase "car was demonstrated", so we use the simple past tense in second phrase as well, hence A and B are out.
IMO C
Original range is 112 - 45 = 67
Now, after selling 20 shares of X, X will be 36
and after buying 24 shares of Y, Y will be 118
So, new range is 118 - 36 = 82
So, increase in range = 82 - 67 = 15, that is D.
