Answer
B: membrane
Explanation
## Step 1The viral envelope is a layer that surrounds some viruses. This envelope is not part of the virus itself, but it contains lipids and surface proteins. ## Step 2The envelope is originally a part of the host cell. The virus acquires this envelope during a process called budding, where the virus exits the cell by pushing a portion of the cell's plasma membrane into the virus. This plasma membrane is essentially the outer structure of a cell.## Step 3Given the information above, the correct answer is B: membrane. This is because the viral envelope is made up of lipids and proteins that were originally part of the host cell's plasma membrane.
