B. No, if it were a Cobb-Douglas production function, the income shares would be constant over time.

Explanation:

The Cobb-Douglas production function is usually used to show the relationship between capital and labor( can be used for other variables) and how much output they can produce at varying levels.

The thing about the Cobb-Douglas function however, is that it assumes a constant rate of income shares overtime. This country's income on the other hand, sees its income shares fluctuating overtime so the Cobb-Douglas function is not a good representation for them.
