Features of Liliaceae:
Liliaceae is a family of flowering plants that includes many familiar species such as lilies, tulips, and onions. Let's analyze the given features to determine how many of them belong to the Liliaceae family.

1. Endospermous:

2. Actinomorphic:
Actinomorphic means that the flowers are radially symmetrical, with multiple planes of symmetry. This feature is common in the Liliaceae family, as many species within this family exhibit actinomorphic flowers.

3. Basal leaf:
Basal leaves are those that arise from the base of the plant, close to the ground. This feature is also not specific to the Liliaceae family and can be found in various plant families.

4. Epipetalous:
Epipetalous refers to the stamens being attached to the petals of the flower. This feature is not exclusive to the Liliaceae family and can be found in other plant families as well.

5. Bicarpellary:
Bicarpellary means that the ovary of the flower is composed of two carpels. This feature is common in the Liliaceae family, as many species within this family have bicarpellary ovaries.

6. Superior ovary:
Superior ovary means that the ovary is positioned above the attachment point of other floral parts. This feature is not specific to the Liliaceae family and can be found in various plant families.

7. Reticulate venation:
Reticulate venation refers to the presence of a network-like pattern of veins on the leaves. This feature is not exclusive to the Liliaceae family and can be found in other plant families as well.

8. Glabrous:
Glabrous means that the plant is devoid of hairs or trichomes. This feature is not specific to the Liliaceae family and can be found in various plant families.

Conclusion:
Out of the given features, only two are exclusive to the Liliaceae family: Actinomorphic flowers and bicarpellary ovaries. Therefore, the correct answer is option 'A' - Four features belong to the Liliaceae family.
