Step 1: Recall the three budgetary objectives (Musgrave):
Allocation function, distribution function, and stabilisation function.
Step 2: Map each option to an objective:
"Allocation of resources" is literally the allocation function; "Inequalities" is addressed by the distribution function (progressive taxation, subsidies to the poor); "Inflation" is addressed by the stabilisation function (adjusting total budgetary spending/taxation to manage demand).
Step 3: Since all three map to real budget objectives:
None can be excluded, so the comprehensive option is correct.
Final Answer:
Option D, all of these.
