by the way Rhade why would naval capabilities affect MRCA, the Eurofighter's naval version is only concept and it made it to the final round, also India had already ordered Mig-29K and is developing Naval Tejas, I do agree with your other points though
That's easy, they are in the middle of upgrading whole air force. In that case if you will buy the same fighter for air force and naval air force you save a lots of money. The same parts, the same weapons ect: Rafael is both, thats why he probably win MRCA, buy one get one free.
Rest is just a elimination process, 3-2-1, Gripen was just first who get out from it.
