The correct option is
B Glaucoma
Glaucoma is not cancer but an abnormality of the eye which is caused due to an increase in the fluid pressure that leads to the permanent damage of the optic nerves and consequently irreversible loss of eyesight. It is characterized by the symptoms such as eye pain, blurred vision, headache, nausea, vomiting. Whereas leukaemia is the cancer of blood and bone marrow, carcinoma is a cancer of epithelial cell and sarcoma is the cancer of connective tissue and other non-epithelial tissues. Thus, the correct answer is option B.
