Answer: D. Smedley has a Cobb-Douglas utility function.

Explanation:

Utility is the satisfaction that a customer gets when he or she uses a particular good or service.

Since we're informed that regardless of his income and regardless of prices, Smedley always spends 25% of his income on housing, 10% on clothing, 30% on food, 15% on transportation, and then spends 20% on recreation, this behavior is consistent with a Cobb-Douglas utility function.

In this case, the goods aren't perfect substitute as they do not serve safe function. Also, Smedley doesn't consumes all goods in fixed proportions. Therefore, the correct option is D.
