Consider the following pairs: Plant : Description I. Cassava : Woody shrub II. Ginger : Herb with pseudostem III. Malabar spinach : Herbaceous climber IV. Mint : Annual shrub V. Papaya : Woody shrub How many of the above pairs are correctly matched?

Cassava (Manihot esculenta) is a woody shrub, so I is correct. Ginger is a herb with a pseudostem-like aerial shoot formed of leaf sheaths (the true stem is the underground rhizome) — however, the typical botanical description of ginger calls it a rhizomatous herb, not strictly a 'herb with pseudostem' (that description fits banana better), so II is not correctly matched. Malabar spinach (Basella alba) is a herbaceous climber, so III is correct. Mint is a perennial herb, not an annual shrub, so IV is incorrect. Papaya is a tree-like herb (sometimes called an arborescent herb), not a woody shrub, so V is incorrect. Only two pairs (I and III) are correctly matched.
