Concept:Holistic means viewing something as a complete, connected system rather than focusing on separate parts.
Explanation:This word is used when the whole system matters more than its individual pieces.
For example, holistic health looks at mind, body, and life together, not just one symptom.
Option A matches this meaning because it talks about "complete systems rather than individual parts".
Option B is wrong because it limits the meaning to only certain industries.
Option C is wrong because routine tasks have no connection to the complete-system idea.
Option D is wrong because it confuses "holistic" with "holy", which relates to religious rituals.
Thus, the correct meaning is the first option.
Answer:A. Relating to complete systems rather than individual parts
