To solve matching questions, focus on the specific traits of plants:
Salinity tolerance is common in mangrove species like Rhizophora.
Arid zone habitats often feature drought-resistant plants like Tribulus.
Drought tolerance is characteristic of trees like Casuarina.
CAM plants like Opuntia are adapted to conserve water by opening stomata at night.
I. Tolerate salinity: The correct match is D. Rhizophora.
Rhizophora, a mangrove species, thrives in saline conditions and is well-adapted to tolerate high salt levels in coastal environments.
II. Arid zone habitat: The correct match is A. Tribulus.
Tribulus is a plant commonly found in arid and semi-arid regions. It is well adapted to surviving in hot and dry conditions with limited water availability.
III. Drought tolerant: The correct match is B. Casuarina.
Casuarina, also known as Australian pine, is a drought-resistant tree species. It has adaptations that allow it to thrive in dry and drought-prone environments.
IV. CAM plant: The correct match is C. Opuntia.
Opuntia, a cactus species, is a CAM (Crassulacean Acid Metabolism) plant. It is adapted to arid conditions by opening its stomata at night to minimize water loss during the hot daytime.

Approach Solution -2
To solve the problem, we need to match the items from List A with their corresponding items from List B.
1. Understanding the Concepts: Each item in List A corresponds to a particular characteristic of plants, such as their habitat, tolerance, or type of metabolism. We need to match these characteristics with the correct plant species from List B.
2. Analyzing Each Pair:
Tolerate salinity: Plants that tolerate salinity are typically found in coastal or saline environments. The correct match for this is "Rhizophora," which is a mangrove plant known for its salinity tolerance. Thus, I → D.
Arid zone habitat: Plants in arid zones are adapted to dry, desert-like conditions. "Casuarina" is a tree that thrives in such conditions. Thus, II → A.
Drought tolerant: Plants that are drought-tolerant are adapted to survive in dry conditions. "Opuntia," a type of cactus, is known for its drought tolerance. Thus, III → B.
CAM plant: CAM plants are known for their ability to perform photosynthesis in dry, arid conditions by conserving water. "Vallisneria" is a type of aquatic plant that uses the CAM pathway. Thus, IV → C.
3. Checking the Options: Based on the analysis above, the correct matching is:
I → D (Rhizophora)
II → A (Casuarina)
III → B (Opuntia)
IV → C (Vallisneria)
Final Answer: The correct answer is (A) I-D, II-A, III-B, IV-C.
