Explanation / Answer

Answer will be option A, B, C and D that is contractility increases in sympathetic drives because increased cAMP causes more HCN channels open, steeper Ramp potential, faster sodium ion influx and more active PKA. Increased level of cAMP activates PKA (phosphokinase) that directly activate HCN channels and other target protein. Protein phosphatase deactivate HCN channels and inhibit phosphodiesterase that break cAMP. HCN channels act on rhynodine receptor. Calcium ion have main role in muscles contraction.
