Answer:
CD4 on the surface of helper T-cells.
Explanation:
MHC class II ( major histocompatibility complex) molecules are processed from the exogenous source. The presentation of antigen on cells are important for the adaptive immune response.
MHC class II interact with CD 4 present on the surface of T helper cells. This interaction is important for the generation of an immune response. Helper T cells can release cytokines and can perform phagocytosis.
Thus, the correct answer is option (C).

I do not understand your question fully because there might be some context missing to it:
Having more nuclei is not something caused by the lack of a process or stage. Some muscle cells usually fuse together, which means they become one. But before they became one, each had their own nuclei. And when they fused, each one kept their nuclei, making one cell with more than one nuclei.
Those cells are called multinucleated cells.
