The Correct Option is B

Solution and Explanation

Concept: Use Kirchhoff’s Voltage Law (KVL).

Step 1: Analyze circuit
Two voltage sources:
• Left source = $10V$
• Right source = $5V$

Step 2: Voltage across resistor
\[ V_{resistor} = 10 - 5 = 5V \]

Step 3: Required voltage
Terminal voltage $V$ equals difference. \[ V = 5V \] \[ \therefore \text{Correct answer is (B)} \]
