c) Matboard
d) Rag mats

Answer 1

Rag mats are the only type of naturally acid-free/lignin-free mats. Correct answer is option d. Rag mats

Step-by-step explanation:

Rag mats are the only type of naturally acid-free/lignin-free mats. This means that they are made from cotton or linen fibers, which do not contain acids or lignins that can cause deterioration over time. The absence of these harmful substances makes rag mats an excellent choice for preserving artworks, photographs, and other delicate items.

Rag mats are crafted from high-quality cotton or linen fibers, making them inherently acid-free and lignin-free. This characteristic ensures that these mats won't contribute to the deterioration of the items they frame, making them a preferred choice for preserving valuable artworks or photographs.

Correct answer is option d. Rag mats
