Option B is correct.

Step-by-step explanation:

Given: Distance Sonya want to walk = 2.5 km

Distance around pool = 0.05 km

Distance around running track = 0.4 km

She walked 4 times around the track.

To find: Additional kilometers she need to walk.

Distance cover by Sonya in 4 round around track = 4 × 0.4 = 1.6 km

Distance left to cover = 2.5 - 1.6 = 0.9 km

Therefore, Option B is correct.

B is correct.
