The correct answer is option 2, Stress.

Pressure is defined as force per unit area, and its unit is Pascal (Pa) in the metric system. Stress, on the other hand, is also defined as force per unit area. This means that the unit of Stress is also Pascal (Pa), which is the same as the unit of Pressure.

Option 1, Angular momentum, has the unit of kilogram meter squared per second (kg·m²/s), which is not the same as the unit of pressure.

Option 3, Strain, is a dimensionless quantity and does not have a unit. Therefore, it does not have the same unit as that of pressure.

Option 4, Work, has the unit of Joule (J) in the metric system, which is not the same unit as that of pressure.

Therefore, the correct option is option 2, Stress, which has the same unit as that of pressure.
