Answer: The correct answer is Option C.
Explanation:
Energy of the Electromagnetic Spectrum is given by the Planck's equation:
Where,
E = Energy of the wave
h = Planck's constant
= Frequency of the wave
And we know that,
where,
c = Speed of light
= Wavelength of the wave
Putting the value of frequency in energy equation, we get:
From the above relation, we get that energy is inversely related to wavelength of the wave.
From the spectra, we know that order of wavelength follows:
Infrared > Visible > UV
So, the order of energy gets reversed and the order becomes:
Infrared < Visible < UV
From the above information, we conclude that the correct option is Option C.

Explanation :
The heating curve shows how water changes from one state of matter to another based on temperature and the addition or removal of heat over time.
Initially, ice is heated until its temperature reaches and changes to liquid state.
From the attached graph it is clear that until the temperature will rise steadily. Here, the liquid begins to vaporize. Vaporization is the state of matter at which liquid state changes to the gaseous state.
So, E is the point which shows the gaseous state.
