Question

The presence of an amoeba stange in both the life cycles of Rhizaria and Unikonta Super Groups:

Indicates that they share a common ancestry

Is not meaningful in showing relationships since the amoeba form has evolved more than once in unrelated organisms

That in both Super Groups, the amoeba stage feeds by phagocytosis

Both b and c are correct

Answer 1

The presence of an amoeba stage does not indicate any kind of common ancestry. Please note that amoeba has evolved many times. The amoeboid cells occur not only in Protista, but also in various algae, fungi and even animals. So, option 'b' is correct.

Note that in all amoeboids, the primary mode of feeding is phagocytosis. So, in both the given super groups (Rhizaria and Unikonta), the mode of feeding is phagocytosis. So, option 'c' is correct.

So, the correct answer is option d (Both ‘b’ and ‘c’ are correct).
