The correct option is B i.e total displacement

Draw a vector from his starting point to his ending point.

Explanation:

Displacement:

A displacement is a vector whose length is the shortest distance from the initial to the final position of a point.

Here we will have figure below

Where

A is a initial point from where Mark walked 2 miles east till point B.

Then 1 mile to North till point C.

Therefore point C is the final point.(or end point)

Here

So his total displacement will be given by drawing a vector from his starting point to his ending point.
