Answer:
The correct answer is letter "B": availability.
Explanation:
Availability bias or availability heuristic refers to individuals tending to relate the easiest judgment they can recall about a certain matter as its most suitable metric and even a metric that could predict future behavior on that topic. This happens because those people make assumptions based on what they can remember of that matter which might not be necessarily the most accurate input about it.
Therefore,<em> if a manager is measuring performance only placing focus on employees' recent and not past behavior, the manager is implementing availability bias.</em>
