To find the value of R, we use Ohm's Law, which relates voltage (V), current (I), and resistance (R).

Identify the given values from the circuit diagram.
We are given:
Voltage, $V = 9\, \text{V}$
Current, $I = 2\, \text{A}$
Recall Ohm's Law.
Ohm's Law states that $V = I \times R$ .
Rearrange the formula to solve for R.
$R = \frac{V}{I}$
Substitute the given values into the formula and calculate R.
$R = \frac{9\, \text{V}}{2\, \text{A}}$ $R = 4.5\, \Omega$
The calculated resistance is $4.5\, \text{Ohms}$ . Comparing this with the given options, option C is the correct answer.

The final answer is $\text{C) 4.5 Ohms}$ .
