Question

which plant adaptation is most useful at high elevations?
a. large leaves
b. reduced leaf surface area
c. thick bark
d. deep taproots

Explanation:

At high elevations, conditions like strong winds, low - temperature, and low humidity are common. Reduced leaf surface area helps plants minimize water loss through transpiration and also reduces the impact of strong winds. Large leaves would increase water loss and be more damaged by winds. Thick bark is more useful for protection against fire and pests in some other environments rather than specifically for high - elevation adaptation. Deep taproots are more beneficial in areas with deep water sources or poor soil on flat terrain, not a key adaptation for high - elevation conditions.

Answer:

B. Reduced leaf surface area
