  •          A           B           C
    stationery Log Lag
  •          A           B           C
    Lag stationery Log
  •          A           B           C
    Log Lag stationery
  •          A           B           C
    Lag Log stationery

Solution

D.

         A           B           C
Lag Log stationery

When a graph is plotted taking into consideration time on one hand and growth rate on the other hand, a 'S' shaped curve is obtained. It is called "grand period of growth". This total growth period is divided into three stages.
(1) Initial lag phase
(2) Middle log phase
(3) Final stationary phase
