THENTO GROUPTHE VEGETABLES On the BASIS OF HOMOLOGY AND ANALOGY.

WHICH ONE VEGETABLE WILL LEFT ALONE, AND WHY ?

Answer 1

potato, because we can't eat a raw potato

Answer 2

Radish and carrot  are homologous , since they are similar in basic fundamental structure and origin , but dissimilar in function.

Potato and sweet potato also show similar characteristics, but have different origins. Potato is a modified stem meant for storage of food. Sweet potato is a modified root also meant for the storage of food, so they are analogous

So , the left one is onion.
