1. Interaction between ........ are not restricted by MHC molecules.

A) Th cell and dendritic cell
B) Tc cell and target cell
C) NK cell and target cell
D) Th cell amd B cell

... Answer is B) - Tc cell and target cell

The major histocompatibility complex (MHC) is a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules in vertebrates, which in turn determines histocompatibility.

Thus, MHC molecules act as restriction factors, and the interaction between T cells and target is said to be "MHC-restricted."
