Correct option is A
As per
Clause 7.6.1.5 of IS 800:2007, the width of lacing bars is governed by the bolt diameter used for the connection. The code specifies that the width of lacing bars should not be less than thrice the diameter of the bolts used.
For a bolt diameter of d = 16 mm
Minimum Width of Lacing Bar= 3×d = 3×16 = 48
Thus, the minimum width of lacing bars for 16 mm bolts is
48 mm.
