 Which statement is not true for NKT Cells?

#Unit 4. Cell Communication and Cell Signaling
  1. NKT cells, have received a great deal of recent attention and share features with both conventional T lymphocytes and NK cells.
  2. Like T cells, NKT cells have T-cell receptors (TCRs), and some express CD4. Unlike most T cells, however, the TCRs of NKT cells are not very diverse and recognize specific lipids and glycolipids presented by a molecule related to MHC proteins known as CD1.
  3. Like their innate immune relatives, NK cells, NKT cells have antibody receptors, as well as other receptors classically associated with NK cells. Activated NKT cells can release cytotoxic granules that kill target cells.
  4. they can not also release large quantities of cytokines that can both enhance and suppress the immune response. They appear to be involved in human asthma, but also may inhibit the development of autoimmunity and cancer

A researcher performed an experiment during vulva formation in C.elegans;
I- In first experiment destroyed anchor cell 
II- In second experiment destroyed three central VPCs 
What kind of conclusion has been drawn by these experiments?
a) I-Three cells out of six of the equivalence group divide once and contribute to the vulva formation
b) I-all six cells of the equivalence group divide once and contribute to the hypodermal tissue
c) II-three outer cells, which normally form hypodermis, generate vulval cells instead
d) II-three remaining cells normally formed hypodermis as usually
