Correct answer
Explanation
Rafflesia (note spelling in option is 'Rafflessia') produces the world's largest individual flower, reaching up to 1 meter in diameter and weighing up to 11 kilograms. Found in Southeast Asian rainforests, it's a parasitic plant with no visible leaves or stems. Sunflowers can grow tall but have smaller flower heads, while dahlias and marigolds are much smaller.
