The A, B and C are essentially three different aircraft, designed for different use cases. They were developed by the same program, designed to share as many parts/technology/software as possible, and to look almost the same... But the differences are larger than simply "the B has an extra lift fan" and "the c has foldable wingtips and a tail hook". The C actually has significantly larger wings and weighs almost 20% more than the A due to the extra strengthening needed for carrier operations. And it needs to carry more fuel to get the same range.
