Solution
The correct option is A It is diploid
Escherichia coli is a unicellular prokaryotic bacteria. It lacks membrane-bound organelles like mitochondria, Golgi complex. It also lacks a true nucleus. It contains the haploid chromosome, a single-stranded circular DNA without a nuclear envelope. E. coli contains one homologue of their single chromosome and are considered to be haploid. They live in symbiotic association in the human intestine. It reproduces asexually by binary fission, budding. However, it also shows the exchange of genetic material through gene recombination. This is done through transformation, transduction and conjugation. Thus, the correct answer is 'It is diploid.'
