The correct answer is: on columns with or without a column head.

Here’s the explanation:

A flat slab is a type of reinforced concrete slab that is supported directly by columns, with or without column heads (also called drop panels). The key feature of a flat slab is the absence of beams, which distinguishes it from other slab systems. The slab can have drops (thickened portions around the columns) to enhance shear resistance and load distribution.

So, the correct options are:
- on columns without column head
- on columns with column head

The option "on beams" is incorrect because flat slabs are specifically designed to be supported directly by columns, not beams.

I think both options A and B are correct.

Because a flat slab is a type of slab without a beam.

A reinforced slab, built monolithically with the supporting column and is reinforced in two or more directions, without any provision of beams is called flat slab.

It is B with a column head. The flat plate slab is directly rested on columns.

It should be both A and B.

Flat slab supported on columns instead of beams, so I think this answer is wrong.

Yes I agree.

Flat slab is never supported on beam. The answer should be A and B.

Flat slab is a beamless slab, slab with or without drops and is supported on a column with or without column head.

A flat slab is a two-way reinforced concrete slab that usually does not have beams and girders, and the loads are transferred directly to the supporting concrete columns.
