Correct Answer - Option 1 : 1 and 2 only

Grillage foundation is a special type of isolated footing (spread foundation) generally provided for heavily loaded steel stanchions and used in the location of poor bearing capacity. The load of the column is distributed or spread to a very large area by means of two or more rolled steel sections (generally I section), each layer laid at right angle to each other. Both the layers of the joists (not column) are then embedded in cement concrete.

There are no two sets of perpendicularly placed steel columns.
