M35 is minimum required concrete for prestressed concrete.
Here 35 is in N/mm2. So convert it into kg/cm2.
N/mm2 = 10 kg/cm2.
So 35 N/mm2 = 350 Kg/cm2.
So OPTION [D] IS CORRECT.

For Post tensioning work minimum grade of concrete as specified in IS 1343 is M35, while for Pre-tension prestressed work grade of concrete specified in IS 1343 is M40.
Clause 6.1 Table 1 IS 1343.
Clause 6.1 Table 1 IS 1343.

Right @Saksham.
The min grade of concrete for pre tension is m40.
The min grade of concrete for pre tension is m40.

M35 for Post-tensioned concrete.
M40 for Pre-tensioned concrete.
M40 for Pre-tensioned concrete.

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.
