(b) 
Explanation:
Let us take the north direction to be the positive y-axis and the east to be positive x-axis.

25.0 km southeast, which implies 
south of east. The y-component will be negative and the x-component will be positive.
Second day:
She starts off at the stopping point of last day. This time, both the y- and x-components are positive.
Therefore, total displacements:
Magnitude of displacements,
Direction,
