Specification errors in programming arise when the requirements or specifications for a system do not accurately reflect the intended functionality. One common pitfall of these errors is failures in redundancy and diversity. Redundancy is critical in ensuring that a system maintains its functionality in the case of failure; when specifications do not adequately account for this, the system may lack necessary backup processes or checks that could prevent single points of failure.

Diversity in programming refers to using different methods and technologies to achieve similar outcomes to avoid systemic errors that can arise from a homogeneous approach. If specifications fail to include diverse solutions, the system could become overly reliant on a singular method or component, increasing vulnerability to failures. Therefore, the correct choice highlights a significant risk associated with specification errors, as they can lead to a lack of sufficient safeguards, ultimately compromising system reliability.
