B. Gap junctions
Объяснение
## Step 1The question is asking about the type of junction that allows electrical coupling between adjacent cells in visceral smooth muscle. Electrical coupling refers to the ability of cells to communicate with each other through the transmission of electrical signals.## Step 2Among the given options, gap junctions are the structures that allow for this type of communication. They are specialized intercellular connections that allow for the direct exchange of ions and small molecules between the cytoplasm of adjacent cells.## Step 3This direct exchange of ions and small molecules allows for the rapid spread of electrical impulses across the muscle tissue, leading to coordinated contraction. The other options, such as dense bodies, intermediate fibers, mechanical junctions, and potassium channels, do not facilitate this type of electrical communication between cells.
