The correct option is C Germ cell
The somatic cell is the cell that forms the body of the organism (except germ cells). The glomerular cell is the epithelial cell. As pituitary forms a part of the endocrine system in brain, its cells do not divide. All these cells mentioned are differentiated and are mortal.
The germ cell is the cell that gives rise to gametes and it acquires the properties similar to that of stem cells i.e., they are undifferentiated cells and hence are immortal.
Thus, the correct answer is option (C).
