To prevent permanent deformation, you need to maximize yield strength (A) and young’s modulus (C).

Wouldn’t you want to minimize Young’s Modulus? The higher the modulus, the more stiff the material is. The question asks to maximize deflection. Improving Yield Strength would make sense, since the more tensile stress it can withstand, the more it can deflect

There is some confusion here, is the goal to maximize deflection or minimizing deflection while avoiding permanent deformation?
If the goal is to maximize deflection, then Young’s Modulus should be minimized and yield strength should be maximized so it can deflect more while avoiding permanent deformation(Although stresses should remain under endurance limit considering cyclic loading for very large number of cycles to avoid failure)
If the goal is to minimize deflection and avoid permanent deformation, then Young’s Modulus should be maximized and also maximize yield strength to avoid permanent deformation (again stresses must remain under endurance limit for very large number of loading cycles )
