Answer:
Option C, Venn Diagram
Explanation:
Venn diagram is a mathematical logical relationship that represents the relationship ship between two or more set of data through intersecting circles. The intersection area between the circles represent the similarities between the different set of data while the non-intersecting area of the circle represent the individualistic characteristics of each data set.
Hence, the characteristics of whale and dolphin can be represented by two circles in which the intersecting area of the circle will contain the similarities between the whale and dolphins and the non-intersecting areas will contain their individual unique characteristics.
