Answer and Explanation:
The correct answer is B.
Grade and quality are the two different concepts. The grade is a category or rank used to distinguish items that have the same functional use but do not share the same requirements for quality. The grade is known as the design of a product, relating to its features and technical characteristics, so the degree of grade does not indicate a problem. In other words, grades could be low, medium, or high-grade and not present a problem. Low-grade software might mean that it has limited features. On the other hand, quality is the degree to which the functions of a product meet the requirements. Low-quality software could mean many software defects or a poorly organized, incomplete, or inaccurate user manual. Low quality is considered a problem.
Details for each option:
A. Low-grade software of high quality
Incorrect. Low-grade software means that design software has limited features and high quality implies no obvious defects. Therefore, it does not present a problem.
B. High-grade software of low quality
Correct. Low-quality software means its features or functions do not meet the requirements, and it causes many defects during usage. Low quality is always a problem regardless of its grade.
C. High-grade software of high quality
Incorrect. High-grade software means the software has numerous features, while high quality means that it meets the predefined requirements with no obvious defects. High-grade software with high quality is not a problem.
D. Medium-grade software of high quality
Incorrect. As grade reflects the intended design of a product, it could be low, medium, or high-grade and does not present a problem. Providing software of high quality is not a problem.
