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
