Solution

The correct option is C Both the statement A and B are correct and statement B is the correct explanation of statement A.
These so-called 'unculturable' bacteria don't grow under laboratory conditions, making it impossible to characterise and understand them. Well-behaved bacteria on an agar plate. Non-culturable bacteria just do not grow on these traditional mediums.
So, the correct option is A. ( Both the statement A and B are correct and statement B is the correct explanation of statement A )
