To find the combined resistance of the circuit, we first need to determine the equivalent resistance of the parallel arrangement of the two 2-ohm resistors.

1/R_parallel = 1/2 + 1/2
1/R_parallel = 1
R_parallel = 1 ohm

Now we have a series circuit with a 6-ohm resistor and a 1-ohm equivalent resistor:

Total resistance = 6 + 1
Total resistance = 7 ohms

Therefore, the combined resistance of the circuit is 7 ohms, which is option (a).
