A reinforced slab built monolithically with the supporting columns and is reinforced in two or more directions, without any provision of beams, is called a____
Show Hint
Flat slab:
\[
\boxed{
\text{Slab directly supported on columns without beams.}
}
\]
Drop panels and column capitals may be provided to improve shear resistance.
Step 1: Recall the definition of a flat slab.
A flat slab is a reinforced concrete slab that rests directly on columns without the use of supporting beams.
Step 2: Identify the given structural system.
Since the slab is built monolithically with the supporting columns and no beams are provided,
\[
\boxed{\text{It is a flat slab}.}
\]
Hence,
\[
\boxed{(B)}
\]
is the correct answer.
