Explanation:

Conical Bar vs Prismatic Bar:
- In a conical bar, the cross-sectional area varies along its length, whereas in a prismatic bar, the cross-sectional area remains constant along its length.

Elonagation Under Self-Weight:
- When a bar is subjected to its own weight, it experiences a tensile force along its length causing elongation.
- The elongation of a bar is directly proportional to the force applied and inversely proportional to the cross-sectional area.

Comparison:
- In a conical bar, the cross-sectional area decreases towards the thinner end, resulting in less force being distributed along its length compared to a prismatic bar.
- As a result, the elongation of a conical bar under its own weight is one third of that of a prismatic bar of the same length.

Therefore, the correct answer is option 'C' - one third of a prismatic bar of the same length.
