Step 1: Understanding the Question:
The question tests a core concept from the Nature/Principles of Management syllabus.
Step 2: Identifying the correct option:
Management has a systematic, organised body of knowledge based on general principles (the 'science' aspect), and it also requires the practical, creative application of these principles to specific situations using personal skill (the 'art' aspect). It is universally accepted as both.
Step 3: Why (A) A Science is incorrect:
This ignores the personal, creative skill every manager applies while implementing principles — management is not purely theoretical.
Step 3: Why (B) An Art is incorrect:
This ignores the systematic body of knowledge (principles, theories) that management rests on.
Step 3: Why (D) None of these is incorrect:
Management clearly exhibits characteristics of both a science and an art, so this is factually wrong.
Final Answer:
Both Science and Art
