List-I	List-II
Principle of Management	Explanation
(A) Harmony, Not Discord	(I) Scientific selection of the workers
(B) Cooperation, Not Individualism	(II) Management and workers should realise that each one is important.
(C) Replacing the Rule of Thumb with Science	(III) Competition should be replaced by cooperation, by realizing that they need each other.
(D) Development of Workers	(IV) Scientific methods are used by unifying the best practices and developing a standard method.

Choose the correct answer from the options given below:

Option 1 -> This incorrectly matches Development of Workers with scientific methods (IV), Cooperation with worker selection (I), and Science with cooperation (III).

Option 2 -> This incorrectly pairs Harmony with worker selection (I), Science with management-worker importance (II), and Development with scientific methods (IV).

Option 3 -> This correctly matches: Harmony with mutual importance (II), Cooperation with replacing competition (III), Science with scientific methods (IV), and Development with worker selection (I).

Option 4 -> This incorrectly matches all principles - Harmony with cooperation (III), Cooperation with methods (IV), Science with selection (I), and Development with importance (II).

Hence, Option 3: (A) - (II), (B) - (III), (C) - (IV), (D) - (I) -> Harmony, Not Discord aligns with management and workers recognizing each other's importance; Cooperation, Not Individualism matches with replacing competition through cooperation; Replacing Rule of Thumb with Science corresponds to using scientific methods and standard practices; Development of Workers relates to scientific selection of workers -> correct
