1. A. Only one
2. B. Only two
3. C. Only three
4. D. All four

Answer: D

Explanation

1. Some mushrooms have medicinal properties: Correct. Many mushroom species, such as Reishi, Shiitake, and Oyster mushrooms, are known for their medicinal compounds, including anti-cancer, anti-inflammatory, and immune-boosting properties. 2. Some mushrooms have psychoactive properties: Correct. ‘Magic mushrooms’ containing compounds like psilocybin and psilocin are known for their hallucinogenic effects. 3. Some mushrooms have insecticidal properties: Correct. Certain mushrooms produce secondary metabolites that act as natural insecticides, deterring or killing insects. For example, some species of Lactarius are known to have insecticidal compounds. 4. Some mushrooms have bioluminescent properties: Correct. Several species of mushrooms, particularly in tropical and subtropical regions, exhibit bioluminescence, emitting light through chemical reactions. This phenomenon is often thought to attract insects for spore dispersal. Therefore, all four statements are correct.
