Expert Answer:

### The resistance in the middle has no contribution during the charging process of capacitor C as it does not change the potential difference across RC combination nor the current flowing through it.
Thus, time constant
t_{1} = RC ...(1)
Discharging of the C takes place R+R = 2R (resistors are in series)
thus,
t_{2} = R_{eq} C = 2RC ...(2)
Thus,
From (1) and (2),
Thus, both options (a) and (b) are correct.

_{1}= RC ...(1)

_{2}= R

_{eq}C = 2RC ...(2)
