Explanation: 

Detailed explanation-1: -D) 3, 4, 2, 1 . Reception-transduction-amplification-response. (signal transduction pathways occur in cellular level, reception is when particular ligand binds to receptor in cell membrane, which cause tr…

Detailed explanation-2: -In effect, signal transduction is said to have three stages: First, reception, whereby the signal molecule binds the receptor. Then, signal transduction, which is where the chemical signal results in a series of enzyme activations. Finally, the response, which is the resulting cellular responses.
