C... because displacement is a vector, you need to specify a distance AND a direction (that is why A is wrong). You know it moved 20 m in one second from the stated velocity.

the displacement as vector so the answer should be C;
i.e. 20 meters east ; as direction is necessary

Displacement from the original point is 20meters east but the displacement at that point is 0

C, 20. meters east.
(B AND D ARE VELOCITIES.AND IN A YOU HAVE NOT MENTIONED DIRECTION.)

You have the distance and the direction given to you already

oops confused myself...
displacement does involve a direction so C
ps here is your test
