Spanish day is the common name for which plant?

Answer: Option D

Spanish day is the common name for the Yucca plant.
Yucca is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40 - 50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers.
The Aztecs living in Mexico since before the Spanish arrival, in Nahuatl, call the local yucca species (Yucca gigantea) iczotl, which gave the name Spanish izote or Spanish day.
