Choosing a developer in liquid penetrant testing is critical, as it plays a key role in the effectiveness and reliability of the inspection process. The correct answer emphasizes the importance of compatibility with the penetrant used and the developer's effectiveness in highlighting indications.

When a Level 3 technician selects a developer, it is essential to ensure that it is compatible with the specific penetrant being used. Compatibility helps in attaining a clear contrast between the penetrant indications and the background, making it easier to detect flaws. If the developer does not interact properly with the penetrant, the indications may be obscured or inadequately highlighted, leading to potential flaws going undetected.

Additionally, the effectiveness of the developer in revealing indications is paramount. A good developer should draw out the penetrant from the flaws to the surface where it can be visualized. This ensures that any defects present are adequately highlighted for examination. Factors such as sensitivity and application method also come into play here, ensuring that the process yields reliable results.

Other criteria, while they may have some relevance, do not take precedence over the fundamental requirements of compatibility and effectiveness in highlighting indications. Thus, focusing on these technical properties is crucial for achieving accurate inspection outcomes.
