Answer:

option D.

Explanation:

The Correct answer is option D.

Pretensioned concrete is the advance method of concreting. This method is used for large construction.

In this method, Tendons are inserted in the steel cage before casting. The tendons are stressed with the help of jack.

When the tendons are stressed then concreting is done. This process is used to increase the strength of the structure.

The load-bearing capacity of Pretensioned material is far greater than normal concrete material.
