Solution

Meiosis is a double division that occurs in a diploid reproductive cell in which nucleus divides twice but chromosome replicate only once to form four haploid cells, each having the half number of chromosomes present in the parent cell. It causes reduction. It is also known as reductional division and meiosis was first demonstrated by Van Beneden. The term was given by Farmer and Moore.
Thus, the correct answer is 'Farmer and Moore.'
