The Positional Advantage in Rook Endings

One type of structural advantage is fewer pawn islands. Pawns can also be isolated, doubled or just easy to attack.

Here is a nice example of multiple types of pawn weaknesses with equal material in double rook ending.

White to Play(Diagram)

White has the healthier structure and plenty of targets. Both rooks are actively placed on the c-file and the a-pawn is isolated. The doubled g-pawns are not attackable but have reduced flexibility.

White is attacking the c6-pawn while Black is also attacking the e-pawn.

What do you recommend for White? This is not a single solution question. There is more than one good move.
