A) Elevation of intracellular cAMP levels, leading to the activation of protein kinase A
B) Elevation of PIP₃ levels in the plasma membrane, leading to the activation of protein kinase B
C) Elevation of intracellular Ca²⁺ levels, leading to the activation of protein kinase C
D) Elevation of IP₃ in the plasma membrane, leading to the activation of protein kinase D
E) Elevation of intracellular cGMP levels, leading to the activation of protein kinase G
