Which option below means the projects, processes and products meet written specifications?

i feel Option C is more holistic in scope because by Quality Conformance all  aspects get covered during QC/QA checks.

Option A is narrow in scope.

e.g. there may be requirement of one handle  to be put in the vehicle.Now "meeting the specs"  will imply the handle is suuplied.

But what type of handle?size?toughness?rigidity?hardness?These are also important.

Hence  I feel option C is more appropriate.

Out of the Options given above, Option A

Conformance to requirements are meeting specification
