How does the compressive strength of impression plaster compare to that of alginate?

Show Answers

It has lower compressive strength than alginateIt possesses greater compressive strength than alginateIt exhibits similar compressive strength as alginateIt is stronger in compression than hydrocolloids

Explanation

Impression plaster demonstrates less compressive strength compared to alginate, making option A the correct choice. Options B, C, and D incorrectly state that impression plaster has equal or higher compressive strength relative to alginate or hydrocolloids.
