A
Possess the ability to damage host cells.
B
Are released by pathogens into host cells during infection.

Verified step by step guidance1
Understand the role of phospholipases: Phospholipases are enzymes that hydrolyze phospholipids, which are a major component of cell membranes.
Identify the common characteristics of phospholipases: They can damage host cells and are often released by pathogens during infection to disrupt host cell membranes.
Analyze the options given: The options describe various actions or characteristics of phospholipases.
Focus on the exception: Determine which option does not align with the known functions of phospholipases.
Recognize that forming pores is not a typical function of phospholipases: Phospholipases hydrolyze membranes but do not typically form pores, which is a function more associated with pore-forming toxins.
