Complete Answer:
- The Aloe Barbadensis plant is one of the most widely recognised houseplants because of the Aloe Vera gel found within its leaves.
- Under the APG III classification scheme, the family Xanthorrhoeaceae includes the disparate sub-families Asphodeloideae (Asphodelaceae), Hemerocallidaceae (Hemerocallidaceae) and Xanthorrhoeaceae.
- Flowers are normally borne on a leafless stalk shaped by a basal rosette of leaves. The individual flowers have stalks (pedicels) and there is a woody tissue disc (hypostase) at the base of the ovule. The presence of anthraquinones in the Xanthorrhoeaceae is a unifying biochemical characteristic.
- Aloe vera is a stemless or very short-stemmed plant growing to 60–100 cm (24–39 in.) tall and spreading by offsets. The leaves are dense and fleshy, green to grey-green, with some varieties having white spots on the upper and lower stem surfaces.Aloe vera leaves contain phytochemicals under review for potential bioactivity, such as acetylated mannan, polymannan, anthraquinone C-glycosides, anthrones, and other anthraquinones, such as emodin and various lectins.
- Two Aloe vera substances – a translucent gel and its yellow latex – are used in the manufacturing of commercial products. Aloe gel is usually used to produce topical treatments for skin conditions such as burns , cuts, frostbite, rashes, psoriasis, cold sores, or dry skin. Aloe latex is used individually or as a product with other ingredients to be swallowed for relief of constipation.

The correct answer is option (A) Xanthorrhoeaceae.

Note: Ingested aloe products can have adverse drug reactions such as those used to treat blood clots, diabetes, heart disease and potassium-lowering agents (such as Digoxin) and diuretics, among others.
