Solution

The correct option is A $- 5 V$
Step 1: Apply source transformation for $2.5 A$ source.

Step 2: Apply source transformation for $5 V$ source.

Step 3: Apply source transformation for $1 A$ source.

Step 4: Assume current direction as marked and apply KVL.

$2.5 I + 2.5 + 5 I + 2.5 I + 7.5 = 0$
$10 I = - 10$ $∴ I = - 1 A$
$∴ - V p + 5 I = 0$ $∴ V p = - 5 V$
