D

Step 1: Understand the types of quantities in physics. Quantities can be classified as either scalar or vector.
Step 2: A scalar quantity has only magnitude, while a vector quantity has both magnitude and direction.
Step 3: Analyze each option:
- Option A: Displacement - This is a vector quantity as it has both magnitude and direction.
- Option B: Electric field - This is also a vector quantity as it points in the direction of the force experienced by a positive charge.
- Option C: Acceleration - This is a vector quantity since it describes the rate of change of velocity, which has both magnitude and direction.
- Option D: Work - This is a scalar quantity, defined as the dot product of force and displacement, which gives a measure of energy transferred without a direction.
Step 4: Conclusion: Therefore, the correct answer is Option D: Work.
