Correct answer: A
Explanation
The correct answer is Option 1 i.e. longs spans.
The suitability of post-tensioning is particularly good for long spans. Post-tensioning is a technique used in construction to reinforce concrete structures, making it ideal for spans that are longer than traditional methods can accommodate. By applying tension to steel cables embedded in the concrete, post-tensioning helps to reduce the size and weight of the structural elements while enhancing their load-carrying capacity and reducing deflections. This makes it especially effective for large bridges, elevated floors, and long-span beams.
