R₂ and R₃ can be replaced by:
The total R of the circuit is R₁+R₅+R₄ = 706 2/3
So the current in the circuit I=V/R is 100/(706 2/3) = 15/106 A
(I'm deliberately not trying to round the result)
The voltage drop over R₄ is V=I*R = 15/106 * 500 ≈ 70
So answer C would be my choice.

I have more ideas if you're not interested in any of these. :)
This question is related to the emission of electrons when light shines on an metal. (Photoelectric effect)
With the classical theory, it was thought that increasing or decreasing the intensity of light would increase or decrease the kinetic energy of the electron.,
Another expected result was that time gap between when light strikes the metal and when electrons are ejected, would depend on the intensity of such light.
However, the experimental results were not consistent with the particle theory of light. So your answer is A.
Later on this effect was correctly explained by Einstein based on Planck's findings.
Not too sure what the answer the question would expect, or rather what terminology,
But I’d say key-value pairs
For example in CSS
key: value;
color: green;
