According to ISO 9000, what is quality?

Comprehensive and Detailed In-Depth Explanation:

ISO 9000:2015 defines quality as "the degree to which a set of inherent characteristics of an object fulfills requirements."

Clause 3.6.2 (Quality) confirms this definition.

Quality is determined by how well an object (product, service, or process) meets defined requirements (customer, regulatory, or internal).

The other options do not align with the official ISO definition:

Option A refers to performance capability but does not define quality.

Option C describes work conditions, not quality.

Option D focuses on efficiency rather than fulfilling requirements.
