Quality control: Quality control involves the series of inspections, reviews, and tests used throughout the software process to ensure each work product meets the requirements placed upon it. Quality control includes a feedback loop to the process that created the work product. The combination of measurement and feedback allows us to tune the process when the work products created fail to meet their specifications.This approach views quality control as part of the manufacturing process.Quality control activities may be fully automated, entirely manual, or a combination of automated tools and human interaction. A key concept of quality control is that all work products have defined, measurable specifications to which we may compare the output of each process. The feedback loop is essential to minimize the defects produced.
Quality Assurance: Quality assurance consists of the auditing and reporting functions of management. The goal of quality assurance is to provide management with the data necessary to be informed about product quality, thereby gaining insight and confidence that product quality is meeting its goals. Of course, if the data provided through quality assurance identify problems, it is management’s responsibility to address the problems and apply the necessary resources to resolve quality issues.

Software safety: software quality assurance activity that focuses on the identification and assessment of potential hazards that may affect software negatively and cause an entire system to fail.

→ Modeling and analysis process is conducted as part of software safety.

→ Initially, hazards are identified and categorized by criticality and risk.

A. Dynamic metrics are collected by measurements made of a program in execution: This statement is correct. Dynamic metrics involve measuring the behavior and performance of a software program while it is running, often by using various profiling and monitoring techniques. B. Static metrics are collected by measurements made of representations of the system: This statement is correct. Static metrics are derived from the analysis of program representations without executing the code, such as source code or design documents. C. The assessment of software quality is an objective process: This statement is not necessarily correct. Assessing software quality can involve both objective and subjective elements. While some aspects of quality, like adherence to coding standards, can be objectively measured, other aspects, like user satisfaction, can be more subjective. D. An important part of quality assurance is the selection of standards that should apply to the software development process: This statement is correct. Quality assurance involves defining and implementing standards, processes, and practices to ensure that the software development process is carried out in a way that meets quality objectives. So, the correct combination is A, B, and D
