The Correct Option is D

Solution and Explanation

Step 1: Understanding the Concept:
Tapioca, also known as cassava or manioc (Manihot esculenta), is a major root crop grown in tropical regions for its starch-rich storage roots.
Taxonomic classification groups plants into families based on morphological, floral, and genetic characteristics.

Step 2: Detailed Explanation:

Tapioca belongs to the family Euphorbiaceae, which is characterized by the presence of latex, unisexual flowers, and specialized fruits (often three-lobed schizocarps).
Many plants in the Euphorbiaceae family produce latex and cyanogenic glucosides, which are also present in the roots and leaves of raw cassava plants and must be processed out before consumption.
The other families listed in the options are associated with different root and tuber crops:
1. Dioscoreaceae: The family of yams, such as Dioscorea alata and Dioscorea rotundata.
2. Convolvulaceae: The morning glory family, which includes sweet potato (Ipomoea batatas).
3. Araceae: The arum family, which includes taro (Colocasia esculenta) and elephant foot yam (Amorphophallus paeoniifolius).

Step 3: Final Answer:

The family of Tapioca is Euphorbiaceae, which corresponds to Option (D).
