(B) Ilyushin-76
(C) Ilyushin-78
(D) C-130J hercules

Answer 1

Hint: Flying refueling, likewise alluded to as air refueling, in-flight refueling (IFR), aerial refueling (AAR), and failing is the way toward moving flying fuel from one military airplane (the big hauler) to another (the beneficiary) during flight. NATO detailing name Midas is a Soviet four-engined aeronautical refueling big hauler dependent on the Il-76 key airlifted.

Complete answer:
The two primary refueling frameworks are test-and-drogue, which is more straightforward to adjust to an existing airplane, and the flying blast, which offers quicker fuel move, however, requires a devoted blast administrator station.
The methodology permits the accepting airplane to stay airborne longer, expanding its reach or daily time on station. A progression of air refuelings can give range-restricted simply by team weariness and designing elements, for example, motor oil utilization. Since the recipient airplane can be beaten up with additional fuel noticeable all around, air refueling can permit a departure with a more noteworthy payload which could be weapons, freight, or staff: the most extreme departure weight is kept up via conveying less fuel and fixing up once airborne. Then again, a more limited take-off roll can be accomplished because take-off can be at a lighter load before refueling once airborne. Aeronautical refueling has additionally been considered as a way to lessen fuel utilization on significant distance flights more noteworthy than 3,000 nautical miles (5,600 km; 3,500 mi). Potential fuel reserve funds in the scope of 35–40 percent have been assessed for long stretch flights (counting the fuel utilized during the big hauler missions).
The Il-78 big hauler was created and planned in the Ilyushin Aviation Complex in Russia. The principal explanation for its advancement was an extension of the adaptable fuel heap of a prior rendition of the big hauler, the Il-76. The Il-78 has an absolute adaptable fuel heap of 85,720 kilograms (188,980 lb), which incorporates 28,000 kilograms (62,000 lb) from a couple of 18,230-liter (4,010 demon lady; 4,820 US lady) tanks in the cargo hold. In the examination, the Il-76 has a limit of just 10,000 kilograms (22,000 lb). The Il-78 exchanges fuel exclusively through the arrangement of the test-and-drogue refueling technique.

Thus, option (C) is correct.

Note: For the most part, the airplane giving the fuel is uncommonly intended for the errand, even though refueling cases can be fitted to existing airplane plans if the "test and-drogue" framework is to be utilized.
