Option D, uncontrolled cell division

Explanation:

Cancer is a term used collectively for a group of diseases in which the cells of the body start dividing uncontrollably thereby affecting the surrounding cells too.  

Cancer is a genetic disease as it happens by changes in genes which affect the way cell functions. It can be inherited from parents or can also arise due to the changes in the errors that occur during the cells division or when the DNA gets damaged due to environmental affects

Hence, option D is correct

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
