D

Verified step by step guidance1
Understand the role of CD4 molecules: CD4 is a glycoprotein found on the surface of immune cells and is primarily involved in the immune response.
Identify the types of T cells: There are several types of T cells, including Helper T cells (Th cells), Cytotoxic T cells (Tc cells), and Regulatory T cells (Treg cells).
Recognize the function of Helper T cells: Helper T cells, also known as CD4+ T cells, play a crucial role in activating and directing other immune cells, including B cells and Cytotoxic T cells.
Differentiate between CD4 and CD8 markers: CD4 is a marker for Helper T cells, while CD8 is a marker for Cytotoxic T cells.
Conclude which cell type expresses CD4: Based on the understanding that CD4 is a marker for Helper T cells, identify that CD4 molecules are found on Helper T cells.
