Answer

Brief Explanations:

  • Option a: Most rainforest plants have not been tested for cancer - fighting properties. There are millions of rainforest plant species, and only a small fraction has been studied in detail for medical applications.
  • Option b: It is a known fact that about 25% of the active ingredients in cancer drugs come from rainforest plants. For example, taxol (paclitaxel) which is used in cancer treatment was originally derived from the Pacific yew tree (a type of tree that can be found in forested areas, and rainforests are a type of forest ecosystem).
  • Option c: The most powerful anticancer drugs are not exclusively from rainforest plants. There are synthetic drugs and drugs derived from non - rainforest plant sources (e.g., some plants in temperate regions) that are also very effective in cancer treatment.
  • Option d: Since options a and c are incorrect, option d (all of the above) is also incorrect.

Answer:

B. Twenty - five percent of the active ingredients in cancer drugs are from rainforest plants.
