Lithography (C) and Serigraphy (E) are not intaglio techniques. Intaglio involves incising designs into a plate, allowing ink to collect in the grooves. Examples of intaglio techniques include:
Lithography and Serigraphy, however, rely on surface-based techniques, making them distinct from intaglio.
Consider the following statements:
(A) Availability is generally conserved.
(B) Availability can neither be negative nor positive.
(C) Availability is the maximum theoretical work obtainable.
(D) Availability can be destroyed in irreversibility's.
