A column member of length I which cannot sway has a rigid foundation at its bottom. Its top is held with heavy beams. The effective length of the column is
1.51
1.01
0.81
0.651

Answer — 0.651

What is a SLAB ??
A flat, monolithic piece of stone or concrete used for a floor or roof. There are various forms of reinforced-concrete slabs: one-way slabs cast with supporting beams, ribbed slabs cast with series of joists, two-way ribbed slabs (known as waffle slabs), flat plates reinforced in two or more directions without beams or girders, and flat slabs thickened at column supports with drop panels and/or column capitals. A waffle slab supports loads equally well along both axes and is thus most efficiently used to cover square modules . ( Courtesy - britannica )

Can you name this and when it is used ??
