What nickname could be associated with the Ficus Elastica due to its material properties?

The Ficus Elastica is commonly known as the Rubber Plant due to the milky latex sap it produces, which can be processed into rubber. This nickname accurately reflects the plant's material properties, as the latex was historically harvested for commercial rubber production. The plant’s large, glossy leaves are not only visually appealing but also contribute to its hardiness and adaptability in various indoor environments. This trait further solidifies its reputation and association with the term "rubber."

The other options refer to different plants with distinct characteristics. The Corn Plant, for instance, is derived from the Dracaena Fragrans and is named for its corn-like leaves. Dumb Cane relates to the Dieffenbachia species, known for the irritation it causes when ingested. Lastly, the Cast Iron Plant, or Aspidistra elatior, is celebrated for its resilience but has no connection to rubber production or properties. Thus, the nickname "Rubber Plant" not only highlights its botanical attributes but also its historical significance in the production of rubber.
