Which statements are FALSE with regards to surface tension and the definition below?

Question focus: identifying statements that are FALSE about surface tension and the provided definition. 
Option 1: 'The surface tension is greater for systems with weaker intermolecular attractive forces.' This is false because surface tension typically increases with stronger cohesive (attractive) forces at the interface; weaker intermolecular attractions lead to lower surface tension. 
Option 2: 'The surface tension can be thought of as the amount of energy required to increase the surface area by 1 meter square.' This is true. Surface tension is the minimal energy required to create or enlarge a unit area of surface, so it corresponds to energy per unit area (often expressed as gamma, J/m^2). 
Option 3: 'The units of surface tension relate to amount of force for a given surface area.' This statement is misleading and generally considered false in its given form. Surface tension is commonly expressed in N/m (force per length) or equivalently in J/m^2 (energy per area); it is not simply “force per area.” Treating it as a measure of force for a specific surface area mixes two related but distinct interpretations (force per length vs energy per area). 
Option 4: 'The surface tension arises because of a deficiency of attractive intermolecular forces for molecules that are on a surface compared with molecules not on a surface.' This is true conceptually: molecules at the surface experience fewer neighboring interactions, leading to a net inward pull and a surface free energy that manifests as surface tension. 
Option 5: 'The Greek letter for surface tension is gamma.' This is true; gamma is the standard symbol used for surface tension.
