The functional surface molecule on T-lymphocytes that facilitates antigen recognition major histocompatibility complex (MHC) molecules is which one of the following subset of T-cells? 
Select and explain. 
A. T4, B. T11, C. T3, D. T8
D: T8
Answer: D: T8 
Explanation: Surface molecule receptors located on T-lymphocytes allow them individual cellular functions mediated by activation of the presence of specific surface molecules. The subset T-cells, refer to as T8, are T-cells which possess a molecule that facilitates recognition of antigens the MHC molecules. Ref: Levinson W. (2012). Chapter 58.
