gravitational force of earth is given by

so here the force will depend on the product of mass and gravity
so here force will be more if we took the condition of more masses
so here in 3rd figure
there will be maximum force of gravity on it
because it will have 6 boxes so there will be maximum mass
So figure of truck with 6 boxes on it is correct answer
The pictures are not attached, therefore, I cannot give a specific choice.
However, I will try to help you out.
The angle of incidence is defined as the angle formed between the ray of light and the normal to the surface that the ray is falling on.
The angle of incidence can be shown in the attached image.
Therefore, for your question, choose the image on which the above description applies.
Hope this helps :)
Answer:
Since the wire is not splitting at any point in the circuit,
the resistors are in series
Hence, Equivalent resistance = 10 + 20 + 30
Equivalent Resistance = 60 Ω
