Explanation:

Let’s break down the movement step by step:

- The bird starts at the nest.

- It flies 25 m to the North-East (at a 45° angle between North and East).

- It then takes a right turn (from North-East, a right turn leads to South-East) and flies 7 m.

- Next, it takes another right turn (from South-East, a right turn leads to South-West) and flies 75 m.

Now, let’s check the options:

- North-East ? This is the first direction, but the bird moved further.

- East ? This direction does not align with the final turn sequence.

- South-West This matches the final movement direction after two right turns.

- North-West ? This was not a direction taken at any step.

Correct Answer:

Option 3 - South-West
