Answer : The correct option is, 7 m
Explanation :
Distance : It is defined as the how much distance is covered by an object during the motion. It is a scalar quantity that means it does not depends on the direction.
Displacement : It is defined as the change in the position of an object. It is a vector quantity that means it has magnitude and as well as direction.
According to the question,
The distance traveled by jesse towards east = 3.0 m
The distance traveled by jesse towards north = 4.0 m
The total distance traveled by jesse = 3.0 m + 4.0 m = 7.0 m
Hence, the distance traveled by jesse is, 7 m
