Explanation:
Flat slab is a reinforced concrete slab supported by columns without any form of beam. The column strip is a strip of the slab that is adjacent to the column and the middle strip is the remaining area of the slab.
As per Indian Standard Code IS 456:2000, the width of the column strip and middle strip is determined by the following formula:
Column strip width = Effective length of panel / 5
Middle strip width = Effective length of panel / 10
For a panel size of 6m x 6m, the effective length of the panel is the same as the span of the slab, which is 6m.
Using the formula above, we can calculate the widths of the column strip and middle strip as follows:
Column strip width = 6m / 5 = 1.2m
Middle strip width = 6m / 10 = 0.6m
However, as per IS 456:2000, the minimum width of the column strip and middle strip should not be less than half the width of the panel. Therefore, the final widths of the column strip and middle strip are:
Column strip width = Maximum of (1.2m, 3m/2) = 3m
Middle strip width = Maximum of (0.6m, 3m/2) = 1.5m
Hence, option C (3.0m and 3.0m) is incorrect and the correct answer is option C (3.0m and 1.5m).

Given answer C is Correct,
In a Span, there are two Column strips (each has width of span/4=6/4=1.5m) and one middle strip (width=span/2=6/2=3m)
So, as asked widthS of column strips, i.e., (1.5m + 1.5m=3m).
