Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
A good preservative for stone should protect the surface durably. Desirable qualities include easy penetration into the stone, easy application, low cost and long-lasting protection.
Step 1:
Easily penetrating, economical and easily applicable are all positive qualities a preservative should have, so they are desirable.
Step 2:
Leachable means the preservative can be washed or dissolved out by water over time. This is undesirable, because a leachable coating will not last and fails to protect the stone, so it is NOT a quality of a good preservative.
Answer: Option (2) — Leachable.
