Pre-tension = 40 N/mm2.
Post-tension = 30 N/mm2.
Post-tension = 30 N/mm2.

It is not clear from the question whether the prestressed concrete is pre-tension or post-tension.
If pre-tension = 40 N/mm2.
Post-tension = 35 N/mm2.
If pre-tension = 40 N/mm2.
Post-tension = 35 N/mm2.

Pre-tensioned and post-tension is the type of prestress beam.
So, the minimum concrete grade is option D = 350 kg/cm2.
So, the minimum concrete grade is option D = 350 kg/cm2.
