There are two statements marked as Assertion (A) and Reason (R). Mark your answer as per the options given below.

Assertion: Management is termed as group activity.
Reasoning: Every member of a firm joins the organisation with a different purpose but he works towards achievement organisational goals.

Both Assertion (A) and reasoning (R) are correct and but R is not the correct explanation of A.

The correct answer is Option 2: Both Assertion (A) and reasoning (R) are correct and but R is not the correct explanation of A.

Management is a group activity: An organisation is a collection of diverse individuals with different needs. Every member of the group has a different purpose for joining the organisation but as members of the organisation they work towards fulfilling the common organisational goal. This requires team work and coordination of individual effort in a common direction. At the same time management should enable all its members to grow and develop as needs and opportunities change.

The assertion states that management is termed as a group activity, which is correct because management involves coordinating and directing the efforts of a group of people to achieve organizational goals.

The reasoning states that every member of a firm joins the organization with a different purpose but works towards achieving organizational goals is also correct.

While achieving organizational goals is crucial, it's not always guaranteed that individual employee goals perfectly align with them. Management plays a key role in aligning individual goals and aspirations with the larger organizational objectives through effective communication, motivation, and performance management. 

Therefore, while both the assertion and the reasoning are true, the reasoning doesn't fully explain why management is a group activity. It is the collaborative effort and combined skills of various individuals that define management as a group activity, not just the alignment of individual goals with organizational ones.
