Unlike $\alpha$:$\beta$ T cells, $\gamma$:$\delta$ T cells are considered to be components of the innate immune system. One feature of $\gamma$:$\delta$ T cells that leads to their classification as innate cells is:
A) That they migrate from the thymus directly to barrier surfaces such as mucosa and epithelia
B) Their ability to produce pro-inflammatory cytokines
C) That their T-cell receptors are germline encoded rather than a product of VD-J recombination
D) Their rapid turnover in the tissue, with an average survival time of 3-4 days
E) Their ability to make growth factors that act on epithelial cells rather than other hematopoietic cells

C  F1F1F1S1F1F1F10:F1F1F1S1F1F1F10 T cells are considered innate because they migrate directly to barrier surfaces and their T-cell receptors are germline encoded, not a result of VD-J recombination.
