1125 m

1335 m

1200 m

1175 m

1225 m

- The speed of the train is 90 km/h, which is 25 m/s (since 90 km/h = 90 * 1000 / 3600 m/s).

- The train crosses an electric pole in 18 seconds, so the length of the train is 25 m/s * 18 s = 450 m.

- The train crosses a platform in 65 seconds, so the combined length of the train and platform is 25 m/s * 65 s = 1625 m.

- The length of the platform is the combined length minus the train length: 1625 m - 450 m = 1175 m.

- Option 4: 1175 m is the correct answer.
