Solution

The correct option is C $\frac{1}{4}$
Mean = $\frac{S u m o f a l l d a t a}{N u m b e r o f d a t a}$

Sum of all data = $\frac{1}{7}$ + $\frac{1}{7}$ + $\frac{2}{7}$ + $\frac{3}{7}$

= $\frac{7}{7}$ = 1

Mean = 1 $\div$ 4

= $\frac{1}{4}$

Hence, the time that needs to be distributed equally among all subjects = $\frac{1}{4}$ of the total time.
