Answer :

AL2006

Displacement means the straight distance from the start point to the
end point, no matter what route was followed along the way.

The spider ends up 1 meter to the left of where he started, so his
displacement for the trip is 1 meter.

If he returns to the place where he started, then his displacement
will be zero.
