• B. Rigid binding is the most economical.

• D. Saddle-stitch binding is the most economical.

Answer: (C)

When content changes happen often, you want a binding that keeps costs low and is easy to update. Comb binding delivers on that by using inexpensive plastic combs and a simple punched-hole system, so pages can be added or removed without a complete rebind. This makes it practical for frequent revisions and moderate page counts, keeping per-copy costs down in short to medium print runs.

Spiral binding, while sturdy and neat, tends to be pricier per unit and adding pages can be more cumbersome or require new coils, increasing ongoing costs. Rigid binding is a more permanent, durable option but comes with higher setup and material costs, and isn’t convenient for frequent changes. Saddle-stitch binding is the cheapest method but is best for small, simple booklets; as pages grow or updates occur, it becomes less durable and less flexible, making it less economical over time.

So, for materials that need regular updating, comb binding is generally the most economical choice because it combines low cost with easy, quick modifications.
