we've been around this circle many times. From previous threads the range difference between the B and C is less than would be apparent as the C has to bring home enough fuel to hold in the landing pattern and the be able to divert ashore - whilst the assumption is the B will always be able to find a bit of deck to land on and can operate with lower reserves. A RVL allows greater carry back, but weapons can always be dumped for a VL.
The C doesn't have any advantages over the A and has several major disadvantages, in particular the larger wing makes transonic acceleration so slow that its a hazard in combat, and the burner to do will burn up most of the additional fuel if its needed - just as the wrong time...
LM has left the space used on the C for a probe empty on the A to allow a customer to specify it. Though with no trials having been done, leaving the customer to pick up the bill, I am not sure if anyone will do so rather than buy boom equipped tanker(s, or enter into an agreement with someone such as the USAF who already has them.
