D. All of the above

The epicranius is formed by the frontalis and occipitalis.

Explanation:

The epicranius or epicranial muscle covers the skull from the frontal, upper and part of the posterior region, constituted by the frontalis and occipitalis muscles, so it consists of two sections.

Both muscles, the frontalis and occipitalis, are united by a tendinous structure, and give the mobility to the eyebrows, frontal region and scalp.  Separately, the frontalis muscle is related to the facial muscles, while the occipitalis is related to the temporal muscles.

A and B. Temporal and masseter are not part of the epicranial muscle.
