Concept:Xerophytes are plants adapted to dry habitats by reducing water loss.
A water-conserving feature must lower transpiration or store water.
Explanation:A thick cuticle forms a waterproof layer that reduces evaporation.
Sunken stomata trap moist air, decreasing water loss through transpiration.
A fleshy stem stores water for use during dry conditions.
Broad leaves have a large surface area, which increases transpiration and water loss.
Therefore, broad leaves do not help a xerophyte conserve water.
Answer:C. broad leaves
