The pronoun 'that' in A and B, adverb 'again' (C) and the specifics 'Crude prices' and 'the rupee'(E)hint that none of these can be the introductory sentence. Link D-A is established by the word 'expectation' which first 'builds up' (D) and only then 'the government should meet that' (A). (E) follows after 'not yet'(A) because it answers 'then when'. 'And that would be the right moment'(B) follows after (C) which states what this 'that' refers to. So, the sequence is D-A-E-C-B.
