What if option b is 2/9 F and 4 ohm. Is it also an answer?

@Satyam is correct.
Put s = 0, where the capacitor is open circuited, then find the equivalent impedance. After that put s = 0 in given z (s) that is get z (0). Equate this with the previous result and get R and in option, there is only one option with R = 4. So A is the right answer.

Add admittances of cap and res = (S/2)+1.
Then sum res = R+(2/S+2).
Add admittances = (CS)+(S+2/(R*(S+2)+2)).
Total = 3+(R*(S+2)+2))/(CS(R*(S+2)+2)) + (S+2));
Then sum res = R+(2/S+2).
Add admittances = (CS)+(S+2/(R*(S+2)+2)).
Total = 3+(R*(S+2)+2))/(CS(R*(S+2)+2)) + (S+2));

Best explanation will be that at s=0 i.e at w=0 capacitor will be have as an open circuit.
So Z(s) = 8 at s = 0 i.e 4+R+8.
R = 4 ohm.
Of course you can solve it completely also.
So Z(s) = 8 at s = 0 i.e 4+R+8.
R = 4 ohm.
