Decreasing the temperature inside the container.

Reason: For a closed, rigid container the number of moles n and the volume V are constant, so by the ideal gas law P = nRT/V, pressure is proportional to temperature. Lowering T reduces P. The other choices would raise pressure (more moles → higher P; decreasing V → higher P; increasing particle speed → higher T → higher P).
