JEE Main 2010 Mathematics question on Application of Derivatives

Let ff, gg and hh be real-valued functions defined on the interval [0,1][0, 1] by f(x)=ex2+e−x2f(x) = e^{x^2} + e^{-x^2}, g(x)=xex2+e−x2g(x) = xe^{x^2} + e^{-x^2} and h(x)=x2ex2+e−x2h(x) = x^2e^{x^2} + e^{-x^2}. If aa, bb and cc denote respectively, the absolute maximum of ff, gg and hh on [0,1][0, 1], then
