Informal organisation can be better understood with the help of the following features:

(A) An informal organisation originates from within the formal organisation as a result of personal interaction among employees.

(B) The standards of behavior evolve from group norms rather than officially laid down rules and regulations.

(C) Independent channels of communication without specified direction of flow of information are developed by group members.

(D) It has a definite structure or form because it is a complex network of social relationships among members.

Choose the correct answer from the options given below:

Option 1 -> Includes (D) which incorrectly states informal organizations have a "definite structure," contradicting their fluid, spontaneous nature.

Option 2 -> Correctly identifies (A), (B), and (C) as features of informal organizations - they arise from personal interactions, follow group norms instead of formal rules, and use independent communication channels.

Option 3 -> Includes all statements, but (D) is incorrect because informal organizations lack definite structure - they are characterized by their fluid and spontaneous nature.

Option 4 -> Excludes (A) which is a fundamental feature, and includes (D) which incorrectly suggests informal organizations have definite structure.

Hence, Option 2: (A), (B) and (C) only -> Statement (A) correctly identifies that informal organizations emerge naturally from personal interactions within formal settings. Statement (B) accurately describes how behavioral standards come from group norms rather than official rules. Statement (C) properly explains the informal communication channels (grapevine) that develop. Statement (D) is incorrect because informal organizations do NOT have a definite structure - their key characteristic is being fluid, spontaneous, and lacking formal structure, even though they involve social relationships -> correct
