A

Step 1: Understand the circuit shown in the image. It represents a configuration where resistors are arranged in series to create different voltage drops across them.
Step 2: This arrangement is used to obtain a variable potential difference from a total potential difference by using the formula for a voltage divider. The voltage across a resistor in a series is given by the formula:
$$ V = rac{R}{R_{total}} imes V_{total} $$
Step 3: Hence, the correct name for this arrangement is a Potential Divider, as it divides the total voltage into smaller, manageable parts.
Therefore, the correct option is A.
