Final answer:
Non-malignant tumors are characterized by slow growth and are not generally dangerous; they are localized and do not spread to other tissues like malignant tumors do. The correct answer to the question is therefore B).
Step-by-step explanation:
Non-malignant tumors, often referred to as benign tumors, are characterized by being localized and not invading surrounding tissues. Unlike their malignant counterparts which are cancerous, non-malignant tumors typically exhibit slower growth and are generally not dangerous. However, while they do not pose the same level of threat as malignant tumors, which can spread and damage other parts of the body, they might still require medical attention if they grow large enough to cause discomfort or disrupt the function of nearby organs.
The correct answer to the question is therefore B) Slow growth; Not dangerous, although it is important to note that 'not dangerous' does not mean they cannot cause any harm whatsoever.
