Consider the following statement: Assertion (A): Regulative rule of communication tell us what we should and should not do Reason (R): In communication it is essential to structure and coordination interactive. Select e the correct answer from the codes given below:

Both (A) and (R) are true, and (R) explains (A). This comes from communication theory, specifically the Coordinated Management of Meaning framework of W. Barnett Pearce, which separates constitutive rules (what a message means in context) from regulative rules (what we should or should not do in an interaction).

The link is functional. Regulative rules give structure and coordination to interaction: they govern turn-taking, when to speak, and what is acceptable in a conversation. That is exactly the point made in (R), so (R) is the correct explanation of (A).

• Option C is wrong because (R) is a fair description of what regulative rules do.
• Option D is wrong because (A) is a correct definition of regulative rules.
• Option A is wrong because it denies the explanatory link, which is the crux of this question.

Mains angle: rules of communication underpin professional conduct in public administration, such as how officers conduct grievance hearings and official correspondence.

Trap: candidates treat the reason as a vague generic statement and reject the link, when it is essentially the functional definition of regulative rules.
