The following table is based on the work record of 8 workers — L, M, N, O, P,Q, R and S who are working under the supervision of Gopinath on the $$30^{th}$$ September.
A = Talking informally
B = Working sincerely
C = Pretending to work
D = Sitting idle
E = Discussing about work
F = Not at work place
G = Disturbing others
The management allocated points for the workers as follows :
A = -2 : B = 5; C = 1 ; D = 0; E = 4; F = -3; G = 4
The sum of the points of all the workers at a specific time is called the efficiency at that time, then at which of the following times of the day was the efficiency the lowest on September $$30^{th}$$
