Given the fоllоwing clаss аnd the fаiling test lоg, identify the root cause and propose a minimal fix. public class SimpleCounter { private int count = 0; public void increment(int delta) { if (delta > 0) { count = count + delta; } } public int getCount() { return count; } } Test snippet (JUnit-style): @Test public void testIncrementTwice() { SimpleCounter c = new SimpleCounter(); c.increment(1); c.increment(0); assertEquals(1, c.getCount()); } Run output shows the test fails with expected but was . Part A (3 pts): What is the most likely cause of this failure? (one short paragraph) Part B (3 pts): Give the minimal code change to fix the bug (show code snippet). Part C (2 pts): Give one additional short unit test (input + expected) that verifies the fix.
