Which of the following is a way that a molecule releases energy gained by absorption of a photon?
a) heat
b) fluorescence
c) light
d) all of the above

The right answer is all of above.

The photocells or photoresist capture the photons and heat by transforming the photon energy into thermal energy.

Some molecules emit fluorescence when they absorb photons (the emitted light has wavelengths greater than that of the incident light).

Some molecules reflect the unabsorbed light after absorbing incident photon energy, such is the case of all colored materials.
