Which of the following was not a kingdom in Linnaeus’s taxonomy?

In Linnaeus’s original taxonomy, the following kingdoms were recognized:

1. **Animalia** (animals)

2. **Plantae** (plants)

Linnaeus did not include the following kingdoms, as they were introduced later:

– Protista: Added by Ernst Haeckel in 1866.

– Fungi: Recognized as a separate kingdom in the 20th century.

– Monera : Introduced later to include bacteria and similar organisms.

So, any of these options (Protista, Fungi, Monera) were not part of Linnaeus’s original classification system.
