Hello,
The answer should be option D "specific heat".
Reason:
Specific heat is what tells the person how my heat and or pressure is required to raised the objects temperature. Its not option A convection because I'm convection is mainly used as like the ozone layer and the suns rays. Its not option B radiation because radiation doesn't tell the person what temperature it needs in order for it to rise its more like its already rises and hot. Its also not option C because conduction is the process of a object heating another object therefore the answer is option D.
If you need anymore help feel free to ask me!
Hope this helps!

Answer: 9.98 *10^-19 J
Explanation: In order to explain this probelm we have to consider the balance enegy for photoelectric effect.
h*f-W=Ek where h is the Planck constant and W the work function and Ek the kinetic energy. f is the frequency of light.
W=h*f-Ek=6.62*10^-34*2.4*10^15-5.9*10^-19=9.98*10^-19J
