Find the odd one out: Rose, Lotus, Sunflower, Oak, Tulip

Correct — C.
Rule: find the class four of the five share, then the one outside it.

Rose, Lotus, Sunflower and Tulip are all flowers.
Oak is a tree.

Oak is the odd one out → option (c).

Why the others are wrong

• (a)
  Rose — Rose is a flower, like lotus, sunflower and tulip. It belongs to the group, so it cannot be the odd one out.
• (b)
  Lotus — Lotus grows in water, which sets it apart by habitat, but it is still a flower. The split that leaves one item alone is flower against tree.
• (d)
  Tulip — Tulip grows from a bulb, but it is a flower like rose, lotus and sunflower. Oak is the tree.

Odd-one-out items test classification. Name the category that fits most of the items as closely as possible, then check which item falls outside it.

Here four names are flowers, and oak is a tree. Sunflower is in the list but not among the options, so it cannot be the answer. It still helps confirm the flower group.

Key facts

• Oak trees belong to the genus Quercus.
• Oaks are flowering plants, and their male flowers hang in catkins.
• Tulips grow from bulbs.
• The lotus is an aquatic plant.

Common traps

• Picking Lotus for growing in water, a real difference that does not split the list into four and one
• Assuming oak is out because trees do not flower
