It reduces self weight there by reducing bending moment and shear force, increase gap between moment of resistance and bending moment, the research is being carried out still on this process.

Post tensioning is economical for large span and is adopted now a days.

Generally used in T-beam girder bridges if any loading.

Option C is correct. Post tensioning is one methods of prestressing concrete. It is casting concrete first by providing conduit in it, after the concrete is cure enough providing tendons through the conduit and tensioning by using anchor at the two ends abutments.

Post tensioning is economical for large spans and it reduces the size of section and as well reduction in deadweight. So load on the structural member is reduced due to its self weight reduction.

Post-tensioning is a method of reinforcing concrete or other materials with high strength steel bars. Post-tensioning applications include office and apartment buildings, parking structures, sports stadiums, rock and soil anchors & water tanks.

After hardening of concrete, the stretched tendons are released. Hence it will try to regain its position and the hardened concrete will not allow tendons to its original position. This whole setup is known as post-tensioned prestress concrete.
Also there is no contact with tendon and concrete.
