Answer 1

The Correct Option is A

Step 1: Understand the requirement.
We pick the items essential for successful classroom communication from $K, L, M, N, O$.
Step 2: Check Define the purpose (K).
Clear objectives keep communication structured and goal-oriented, so K is essential.
Step 3: Check Use un-risky humour (M).
Gentle, safe humour lowers anxiety and boosts attention, so M is essential.
Step 4: Check Repeat speech-tags (O).
Repeating key cues reinforces ideas and aids retention, so O is essential.
Step 5: Reject Avoid rehearsals (N).
Preparation improves delivery, so avoiding rehearsal is harmful and wrong.
Step 6: Reject Opt only for presentations (L).
Presentations alone, without clarity and engagement, are not sufficient.
Step 7: Combine and conclude.
\[ K + M + O = \text{essential set} \]
This is option A.
\[ \boxed{\text{A. K, M and O}} \]
