Battening is preferable when the i) column carries axial load only ii) space between the two main components is not very large iii) column is eccentrically loaded The correct answer is A. Only (i) B. Only (iii) C. Both (i) and (ii) D. Both (ii) and (iii)

The correct answer is C. Both (i) and (ii).

Battening is a method of reinforcing a column by adding additional members that run perpendicular to the main axis of the column. This can be done for a number of reasons, such as to increase the column’s load-bearing capacity, to prevent buckling, or to improve the column’s lateral stability.

Battening is preferable when the column carries axial load only because it provides additional support in the direction of the load. This is important because axial loads are the most common type of load that columns are subjected to.

Battening is also preferable when the space between the two main components is not very large. This is because battens can help to fill in the space and provide additional support.

Battening is not as effective when the column is eccentrically loaded. This is because eccentric loads cause the column to bend, and battens cannot provide support against bending.

Therefore, the correct answer is C. Both (i) and (ii).
