The latitude of line is тАУve so its terms called by____
Northing
Southing
Easting
Westing
Southing
In surveying, the latitude of a line is defined as its orthographic projection on the reference meridian (North-South line). A positive latitude indicates a line running towards the North and is known as 'Northing', while a negative latitude indicates a line running towards the South and is known as 'Southing'.

L=lcos╬╕ тАФ Latitude of a line
D=lsin╬╕ тАФ Departure of a line
Latitude is calculated using the length of the line (l) and its whole circle bearing or reduced bearing (╬╕) measured from the meridian. The formula L=lcos╬╕ yields a positive value for bearings in the 1st and 4th quadrants (Northward) and a negative value for bearings in the 2nd and 3rd quadrants (Southward).
Latitude represents the length of the projection of a survey line on the North-South axis.
Positive latitude is called Northing (N) and negative latitude is called Southing (S).
Departure is the projection on the East-West axis; positive departure is Easting (E) and negative departure is Westing (W).
Calculation of consecutive coordinates and independent coordinates of stations in traversing.
Checking traverse closure using conditions тИСL=0 and тИСD=0 for closed traverses.
Option A (Northing) corresponds to a positive latitude (+ve).
Option C (Easting) corresponds to a positive departure (+ve).
Option D (Westing) corresponds to a negative departure (-ve).
B is correct тАФ Negative latitude signifies a line directed toward the South, which is conventionally termed as Southing.
Remember the quadrant signs: Quadrant I (+L, +D), Quadrant II (-L, +D), Quadrant III (-L, -D), Quadrant IV (+L, -D) to quickly solve latitude/departure questions in competitive exams.
