Consider this timeline of testing activities:

Requirements -> Design -> Coding -> Unit Test -> Integration Test -> System Test

Which testing activity is shifted left in a shift-left approach?

ASystem Test

BProduction Monitoring

CUnit Test

DUser Acceptance Test

Step-by-Step Solution

Solution:

Step 1: Identify testing phases in timeline
Unit test happens early, system test and acceptance test happen later.
Step 2: Determine which test shifts left
Shift-left means moving testing earlier, so unit test is the correct choice.
Final Answer:
Unit Test -> Option C
Quick Check:
Shift-left test = Unit Test early in cycle [OK]

Quick Trick: Unit tests are the earliest tests shifted left [OK]
