Answer 3

The correct answer is:

Its edges do not have clear boundaries.

Answer 4

To characterize a nebula as diffuse means that its edges do not have clear boundaries. This means that it lacks distinct or defined edges, making it appear to blend or fade into its surroundings. The term "diffuse" in the context of a nebula refers to its overall appearance and structure rather than the type of radiation it reflects. Therefore, option C is the correct answer.
