Since radiation interacts with matter in individual particle-like impacts called photons, why does light seem continuous to us?

A) Each photon is spread out over a large region of space and these regions overlap each other.
B) Because there are so many photons in a light beam and each carries such a small amount of energy.
C) Each photon has a very wide range of energies, and these energy ranges overlap each other.
D) Because of the way that the photons interact with each other.
E) Because there are so few photons in a light beam and because they each carry such a large amount of energy.
