High tensile steel is required because Tensile strength of high tensile steel is in the range of 1400 to 2000 N/mm2 and if initially stress upto 1400 N/mm2 their will be still large stress in the high.

Tensile reinforcement after making deduction for loss of prestress. Therefore high tensile steel is made for prestress concrete.

High strength concrete gives better bond strength to avoid slippage, and high tensile strength avoid Strain.

E is the correct.

High strength concrete but low tensile steel.

Yes @Anvesh. E is the right answer.
