Recently a general principle, called c-extremization, which determines the exact R-symmetry of two-dimensional SCFTs with N = (0,2) supersymmetry was identified. In this note we show that the supergravity dual corresponds to the extremization of the T -tensor of N = 2 gauged supergravity. To support this claim we demonstrate that we recover the expected central charge for five-dimensional U(1)^3 gauged supergravity reduced on a Riemann surface.
