The correct option is: GRATINIC ROCK IN THE OCEAN FLOOR.
Sea floor spreading refers to the process by which molten materials add new oceanic crust to the ocean floor. This process occurs slowly across the earth's middle ocean ridges. Harry Hess formulated an hypothesis to explain the phenomenon of sea floor spreading and all the above options support his hypothesis with the exception of option C.

Answer:
The protein phosphatase-1 dephosphorylates the residues of serine, which are phosphorylated by the protein kinase A. The cyclic-AMP inducible genes are stimulated by CREB that is phosphorylated by protein kinase A. Thus, overexpression of protein phosphatase 1 would prevent their induction.  
Although, protein phosphatase 1 would not influence the function of cAMP-gated ligand channels, as these channels are opened directly by binding of cAMP rather than by protein phosphorylation.
