Which of the following territories was annexed by Lord Dalhousie under the pretext of misgovernance, and not directly through the Doctrine of Lapse?

What was the primary stated reason for the Partition of Bengal in 1905 by Lord Curzon?

Answer 1

Evaporation – because water molecules escape from the surface of the solution causing a level difference

Answer 2

Diffusion – because sugar molecules move freely across the membrane until equilibrium is reached

Answer 3

Sedimentation – because sugar crystals settle at the bottom due to gravity

Answer 4

Osmosis – because solvent molecules move from the dilute solution to the concentrated solution through the semipermeable membrane
