E)Providing a 50% reduction in noise , the newly launched aircraft engine is also providing double-digit improvements in fuel efficiency and emissions having

Analysis:

aircraft engine(S) .... has been hailed (V)
The newly launched ( modifies ) AE
AE is also being modified by a list that presents its merits and/or why it has been hailed .
The intended list is : 50% reduction in noise & double-digit improvements
Now the double-digit improvements is also being described through a sublist : fuel efficiency & environmental emissions

Option A: Incorrect The list and the sublist are stated in a wrong way . As per this choice a 50% reduction in noise ll double-digit improvements in fuel efficiency notll environmental emissions , as then it means that the AE has been hailed for providing environmental emissions--- not the intended meaning.
Option B: Incorrect Similar issue with the lists and their intended meaning as in option A.
Option C: Incorrect We have Subject-Verb Agreement issue. As per the current construction the verb has been hailed has no Subject.

Option D: Correct correct option as per the analysis above.

Option E: Incorrect Having been hailed now is not connected to the subject AE and also not acting as a verb. Moreover, it is now modifying emissions ... which is not correct. As per the current structure there is an issue with the intended meaning .

It's (D).

All other choices have modification errors.

Which part between comma correctly modifies engine .even if one removes comma part the sentence makes complete sense.

Although I got the answer correct, I'm puzzled by what the modifier 'environmental emissions' means. The other two modifiers, 50% reduction in noise and double-digit improvements in FE, seem to make sense. Can someone please explain?

The argument is saying two things
50% percent reduction in noise
And
Double digit improvement in fuel efficiency and environmental emissions

Means suppose earlier fuel emission value was 10percent now it has become 20 percent or 25 percent, double digit improvement

Same goes for environmental emissions as well.

Give kudos if this helps

Thanks for the reply mate. I still have the doubt. 'Double digit improvements' can modify FE as the FE can improve by how much ever %. Environmental emissions can only reduce in this context so 'double digit improvement in environmental emissions' doesn't make sense/sound right to me. Please correct me if I'm going wrong somewhere in my comprehension of the sentence.

Suppose earlier environment emissions constitute 30% but now after new engine it constitutes 15% .in reality it is 15% less

U can say the same thing by "there are double digit improvement in environment emissions"

Hope this helps!give kudos if it does

Subject at start is preferable.D does exactly that.

B -subject comes later after 2nd comma

So when you compare B and D
D is better as subject comes first and makes perfect sense
