Post-tensioning is a form of prestressing. Prestressing simply means that the steel is stressed (pulled or tensioned) before the concrete has to support the service loads. Most precast, prestressed concrete is actually pre-tensioned-the steel is pulled before the concrete is poured. Post-tensioned concrete means that the concrete is poured and then the tension is applied but it is still stressed before the loads are applied so it is still prestressed.

I think the answer will be "C".

(c) is the correct one. Because for larger span bridge post-tensioning system is widely used.

I too think the answer will be "C".

As per my knowledge the correct answer is "C".

Yes, answer C is correct.

I think the correct answer is C.

The correct answer is "is economical for large spans and is adopted now a days".

Option C is right answer.

Post-tensioning is a technique for reinforcing concrete. Post-tensioning tendons, which are prestressing steel cables inside plastic ducts or sleeves, are positioned in the forms before the concrete is placed.
