Which of the following is the correct order of plant species from higher to lower order?

Correct answer: (d) Plant Kingdom - Phylum - Class - Order

Explanation

Taxonomic ranks run from broadest to narrowest as Kingdom → Phylum (Division) → Class → Order → Family → Genus → Species.

Plant Kingdom is the highest, most inclusive level, then Phylum, then Class, then Order.

Only the sequence Plant Kingdom – Phylum – Class – Order follows higher to lower.
