Two kingdom classification was given by 

‘2’ Kingdom classification is a classification given by Carolus Linnaeus. This is done based on mode of nutrition and locomotion

The two-kingdom classification system was proposed by Carolus Linnaeus in the 18th century. This classification divided organisms into two main kingdoms: Animalia (animals) and Plantae (plants). Linnaeus' system was based on a simple distinction between animals and plants, focusing on their basic features and behaviors.

However, this system was later expanded, and more complex classification systems were introduced to account for the diversity of organisms that didn’t fit neatly into these two categories, such as fungi and bacteria. The more advanced classification schemes, like the five-kingdom system proposed by Whittaker, recognized the need for further categorization.

So, the correct answer is option b: Linnaeus, as he was the one who initially proposed the two-kingdom classification system.
