Best answer
Right choice is (b) It is encapsulated

The best explanation: Malignant tumours are a mass of proliferating cells called neoplastic or tumour cells. These cells are not encapsulated. They grow very rapidly, invading and damaging the surrounding normal tissues. Cells sloughed from such tumours reach distant sites through the blood.
