Which question would provide the most objective response regarding mobile device usage?

Choosing the question that asks about the number of mobile devices lost by XYZ Corporation last year yields the most objective response because it seeks a specific, quantifiable piece of information. This type of data can be verified through records or reports, making the answer factual and grounded in real statistics.

In contrast, the other options rely on subjective or qualitative assessments. For instance, inquiries about whether best practices are followed or how secure the mobile device usage policies are depend on personal interpretations and opinions, which can vary widely among respondents. Similarly, asking about the amount of loss suffered requires subjective judgment and estimation, which can lead to significant discrepancies depending on individual perspectives.

By focusing on a tangible metric, the question about the number of lost mobile devices provides concrete evidence that can be analyzed, compared, and acted upon, making it the most objective choice among the options.
