please help me with this question

due tonight

those are the answers choices.

A planar wall has a thickness L, area A, thermal conductivity k, and an internal heat generation egen. If the heat flux into the wall at x=0 is q0, and the temperature at x=0 is known to be T0, find an expression for the temperature profile along the entire wall. Show derivation or explain reasoning for full credit. Hint: QinQout=Egen. a) T(xx)=2kegenx2kq0x+T0 b) T(x)=kegenx2+kq0x+T0 c) T(xx)=2kegen(L2x2)+kq0(Lx)+T0 d) T(x)=kq0x+T0
