|As per IS 456-2000, this is the case of severe exposure condition and for sever exposure condition nominal cover is not less than 45mm. Ref-(Table-3 & Table-16). The nominal cover size may be reduced 5mm for M35 or above concrete grade. So, the answer 'D' may be correct.|

|45 mm but the most probable answer is 40mm.|
|Sourav said: (Nov 22, 2020)|
|According to IS 456:2000 Table 16;
For mild condition, cover should not be less than 20mm and for severe condition(totally immersed in sea water) cover should not be less than 45mm.
So, addition cover in this condition should be 45-20mm=25mm.

|Yes, I agree with you @Sourav.|
|Prasanna Gosavi said: (Sep 17, 2021)|
|Yes, you're totally Correct @Sourav.
So, the correct answer for this question must be 25 mm.
