B)Peripheral membrane protein.
C)Lipid-anchored membrane protein.
D)All of the above.

Peripheral membrane proteins are not embedded in the lipid bilayer and tend to interact with the hydrophilic heads of the phospholipids. Therefore, changes in pH or ionic strength can disrupt these interactions and cause the protein to dissociate from the membrane. Integral membrane proteins and lipid-anchored membrane proteins are embedded in the lipid bilayer and are not affected by changes in pH or ionic strength to the same extent as peripheral membrane proteins.
