Which оf the fоllоwing is the most аppropriаte objective for the requisitioning within the expenditure cycle?

Cоnsider this Inventоry descriptiоn аnd code (shortened): /** * Inventory mаnаges available quantity of items. * * - addItem(String itemId, int quantity): * increases available quantity for the item. * Quantity must be positive. * * - reserveItem(String itemId, int quantity): * if enough quantity is available, reduces available quantity * and returns true; * if the item does not exist or there is insufficient quantity, * returns false. * (Implementation not shown; treat reserveItem as black-box behavior.) * * - getAvailable(String itemId): * returns current available quantity. */ public class Inventory { private Map data = new HashMap(); public void addItem(String itemId, int quantity) { data.put(itemId, data.getOrDefault(itemId, 0) + quantity); // 0 if itemID not in Hash otherwise old value + quantity } // reserveItem implementation intentionally omitted public boolean reserveItem(String itemId, int quantity); public int getAvailable(String itemId) { return data.getOrDefault(itemId, 0); } } Part A (1.5 pts): Identify one primary problematic behavior in the implementation and explain briefly why it is problematic. Part B (2 pts): Identify the main equivalence partitions and boundary values you would consider when testing reserveItem(). Briefly explain why they matter. Part C (2.5 pts): Design 4 test cases for reserveItem(). For each test specify: initial state (available quantity), operations performed, expected result (true/false) and resulting available quantity. Keep them concise (no code). Part D (1 pt): White-box unit test — write a single JUnit-style pseudocode test for addItem behavior (show test body / assertion), and briefly explain why you chose that test case. Keep answers short and concrete.
