The right answer is A. greater leaf surface area.

In botany and agronomy, the specific leaf area (SFS) is defined as the ratio of the leaf area to the dry weight of the leaf (expressed in m².kg-1).

The specific leaf area can be used to estimate the reproductive strategy of a particular plant based on, among other factors, light and moisture levels. The specific leaf area is one of the most widely accepted key features used in the study of leaves.
