The correct choice is (b) False

For explanation I would say: Jean-Baptiste Joseph Fourier (21 March 1768 – 16 May 1830) was a French mathematician and physicist born in Auxerre who was the first person to develop heat equation. The heat equation is the prototypical example of a parabolic partial differential equation.
