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

Cassava is indeed a woody shrub (correct). Ginger has a pseudo-stem formed by leaf sheaths and is a herbaceous plant (correct). Malabar spinach (Basella) is a herbaceous climbing vine (correct). Mint is a perennial herb, not an annual shrub (incorrect). Papaya is technically a large herbaceous plant with a soft, hollow trunk, not a woody shrub (incorrect — it is often classified as a tree-like herb). Hence three pairs are correctly matched.
