\\\\(\ extbf{Correct option:B}\\\\) \\\\(\ extbf{Solution:}\\\\)\\\\(\ extbf{Option (A)}\\\\)\\\\(\\bullet\\\\) Cytoplasmic receptor are present on the surface of the plasma membrane of target cells, the substrate binds to these receptor and conformational change of these receptors brings about further changes inside the cell.\\\\(\ extbf{Option (B)}\\\\)\\\\(\\bullet\\\\) Cyclic AMP acts as a second messenger for steroid hormone as it can not pass through the plasma membrane such as epinephrine and norepinephrine, glucagon, luteinizing hormone, follicle stimulating hormone, thyroid-stimulating hormone, calcitonin, parathyroid hormone, antidiuretic hormone.\\\\(\ extbf{Option (C)}\\\\)\\\\(\\bullet\\\\) Adenosine triphosphate (ATP) is an organic compound that provides energy to drive many processes in living cells such as muscle contraction, nerve impulse propagation and other body functions.\\\\(\ extbf{Option (D)}\\\\)\\\\(\\bullet\\\\) Epinephrine is secreted from the adrenal medulla in response to stress and emergency , as a hormone it increases metabolic rate by accelerating heart rate ,constricting blood vessels ,increasing blood pressure and oxygen consumption. As a neurotransmitter when it transmits impulses at the synapse between axons and dendrites of two neurons.\\\\(\ extbf{Hence, the correct option is (B)}\\\\)
