A,C Correct answer
Explanation

Heat transfer occurs through three fundamental modes: conduction (direct molecular interaction), convection (fluid motion), and radiation (electromagnetic waves). Conduction and radiation are distinct basic modes, while free and forced convection represent different convection mechanisms based on fluid driving forces.
