Final answer:
The key characteristics of a walk through in software development typically include Scenario, Dry Run, and Peer Group, where team members go through a piece of software to review its efficacy before final decisions are made.
Step-by-step explanation:
The question you're asking relates to the key characteristics of a walk through, which is a step in the software development and review process.
Among the options given, the key characteristics of a walk through typically include A. Scenario, Dry Run, Peer Group. During a walk through, a developer or team walks through a piece of software or process with their peers to evaluate its effectiveness.
The scenario is the predefined set of conditions under which the review occurs. A dry run indicates a practice session where the problems are discussed, but no final decisions are made.
Peer group refers to the team members or colleagues who review the work and offer feedback. Pre-meeting preparations and formal follow-up processes may be part of the broader review approach, but they are not as characteristically unique to a walk through as much as scenario reviews, dry runs, and peer group collaboration.
Including metrics, while important to many processes, is not a defining characteristic of a walk through.
