Answer 1

The correct option is (d) Giant colony method

To elaborate: Giant colony method is the most traditional method of the traditional methods of strain characterization. Lindner reported that up to ten single colonies on thick wort-gelatin plates give rise to ‘giant colonies’ when incubated for three weeks at 18°C.
