Pick up the correct statement from the following:
The line which connects a number of parallel tracks, and also provides an access to main track, is called a gathering line
With a diagonal gathering line, the length of the siding decreases with increase of its distance from main track
To have sidings of same length, a diagonal line is laid at one end and a parallel gathering line at the other end
For most economical layout of yards, the gathering lines are laid at the limiting angle
All the above.
