Pick up the correct statement from the following :
the framework which consists of a series of connected lines, the lengths and directions of which are found from measurements, is called a traverse.
the system of a series of lines which forms a circuit which ends at the starting point, is called a closed traverse
the traverse that starts from a point already fixed in some survey system and ends on another such point, is called a controlled traverse
the traverse that is not controlled is called a fly traverse
all the above.
