A strut in a steel truss is composed of two equal angles $$ISA$$ $$150mm \times 150mm$$ of thickness $$100$$ $$mm$$ connected back-to back to the same side of a gusset plate. The cross sectional area of each angle is $$2921$$ $$m{m^2}$$ and moment of inertia $$\left( {{{\rm I}_{XX}} = {{\rm I}_{YY}}} \right)$$ is $$6335000$$ $$m{m^4}.$$ The distance of the centroid of the angle from its surface $$\left( {{C_x} = {C_y}} \right)$$ is $$40.8$$ $$mm.$$ The minimum radius of gyration of the strut is
A
$$93.2$$ $$mm$$
B
$$62.7$$ $$mm$$
C
$$46.6$$ $$mm$$
D
$$29.8$$ $$mm$$

Consider the following two statements related to structural steel design, and identify whether they are True or FALSE.

$${\rm I}.\,\,\,\,\,\,$$ The Euler buckling load of a slender steel column depends on the yield strength of steel.
$${\rm II}.\,\,\,\,\,\,$$ In the design of laced column, the maximum spacing of the lacing does not depend on the slenderness of column as a whole.

A
Both statements $${\rm I}$$ and $${\rm II}$$ are TRUE
B
Statement $${\rm I}$$ is TRUE, and Statement $${\rm II}$$ is FALSE
C
Statement $${\rm I}$$ is FALSE, and Statement $${\rm I}$$$${\rm I}$$ is TRUE
D
Both Statements $${\rm I}$$ and $${\rm I}$$$${\rm I}$$ are FALSE
