• Match Principles of Art and Design:
• Proportion $\longrightarrow$ (IV) Relationship of one part to another or to the whole, or between one object and another (e.g., golden ratio 2:3, 3:5).
• Scale $\longrightarrow$ (III) Sizes of all elements making up the structure have a consistent pleasing relationship to the structure and to each other (relative size in space).
• Harmony $\longrightarrow$ (II) Consonance or pleasing agreement of parts or combination of parts in a composition producing unified aesthetic satisfaction.
• Rhythm $\longrightarrow$ (I) An organized movement in continuity, aiming to produce visual unity through repetition, alternation, or progression.
• Conclusion: A-IV, B-III, C-II, D-I (Option 2).

Correct option: (2) AAV, Bull, C-ll, D-l

• Family Ecosystem Perspective: Boundaries and Interfaces:
• Assertion (A): In the ecosystem perspective of a family, the area which separates a system area of influence from that of other systems is known as a boundary. $\implies$ Correct.
• In human ecological systems theory, a system boundary is an imaginary or tangible perimeter that demarcates the system (family) from its suprasystem (community, environment), regulating energy and information flow.
• Reason (R): A common or shared boundary between systems is called an interface. $\implies$ Correct.
• An interface is the specific point or zone where two systems or subsystems meet and interact (e.g., family-school interface, family-market interface).
• Conclusion: Both (A) and (R) are correct (Option 1).

Correct option: (1) Both (A) and (R) are correct

• Ergonomics of Physical Workspace Arrangement:
• Statement (I): While creating and evaluating physical arrangement for work, location in vertical space and horizontal space has to be considered. $\implies$ Correct.
• Functional workplace planning requires analyzing horizontal work surfaces (normal and maximum horizontal reach envelopes) and vertical zones (vertical reach, eye level, storage heights).
• Statement (II): Location in vertical space evaluates supplies, tools and adjacent work spaces. $\implies$ Incorrect.
• In ergonomics (Barnes and Mundel's principles), supplies, tools, and adjacent work stations are arranged across the horizontal workspace plane (within the normal working area), whereas vertical space evaluates vertical shelves, overhead reach, and bending limits.
• Conclusion: Statement (I) is correct but Statement (II) is incorrect (Option 3).
