15 for slab.
20 for beam.
40 for column.
50 for footing.

25 beam,
20 slab,
footing 50,
column 40 100% sure.
20 slab,

Footing 50 mm above a layer of lean concrete otherwise 75 mm.
Column 40 mm.
Beam 30 mm.
Slab 15 mm.
Column 40 mm.
Beam 30 mm.
Slab 15 mm.

Slab- 20 mm.
But for mild condition and r/f dia is 12mm or less than that time it's consider 15 mm.

Generally,
Slab - diameter of the bar or 15mm whichever is more.
Beam - 25mm.
Column - 40mm.
Footing - 75mm.

According to IS 456:2000.
For main reinforcement up to 12mm diameter for mild exposure, the nominal cover may be reduced by 5mm.
It is also mentioned in code i.e it shall not be less than dia of the bar.
16mm is correct.
