The cells of malignant tumor proliferate, grow rapidly and move to other parts of the body to form new tumors.
This property of cancer cells is called _____________ .

The correct option is B metastasis
Cancer is a disease where cells start dividing uncontrollably and invading the surrounding healthy tissues.
The abnormal, uncontrolled division leads to the formation of a mass of cells called tumors.
Tumours are of two types - benign tumors (non-cancerous) and malignant tumors (cancerous)
Benign tumors - These tumours are localized at a particular location in the body and do not spread to the other parts of the body. Such tumors are generally harmless.
Malignant tumor - These tumours are cancerous meaning that they divide rapidly and have a characteristic feature of spreading to the other normal tissues of the body. This property is called metastasis.
Metastasis is a characteristic property of malignant tumors, it is also the major point of difference between benign and malignant tumors. The spread of cancer cells begins from the site of origin to the other areas of the body via bloodstream and lymph leading to the formation of numerous tumors in other parts of the body. This spread from the primary site of origin of the disease to the secondary site is referred to as metastasis.
Whereas, metagenesis is a pattern of reproduction, where one generation is produced asexually and the next one is produced sexually. This type of alternation of generations is called metagenesis. For example, polyp and medusa are two body forms of coelenterates, polyp produce medusae asexually and medusae from polyp sexually.
Teratogenesis is a prenatal toxicity condition mainly characterised by structural, functional defects in the developing embryo or foetus.
Cell cycle is an orderly sequence of events during which a cell grows, duplicates its genetic material and then undergoes division. Cell cycle includes two phases, interphase and mitotic (M) phase.
The interphase is the time during which the cell is preparing for division by undergoing both cell growth and DNA replication in an orderly manner.
During M phase (mitotic phase), the cell undergoes division and forms into two daughter cells. It includes karyokinesis and cytokinesis. During karyokinesis, there is division of the nucleus. In cytokinesis, there is division of cytoplasm resulting in two daughter cells.
