Explanation:

Mrs. Bhalla is facing the problems of overcrowded classrooms and classroom management. Moreover, she wants the students to develop more sensitive and self motivated learners. In such a scenario, encouraging students for self-learning or making them compete will not make any difference to the problem at hand. Actions 3] and 5] are thus eliminated. This eliminated options [1], [2], [4], [5]. We are left with option [3]. Actions 1], 2] and 4] are appropriate steps for Mrs. Bhalla to carry out.
Hence, the correct answer is option 3.
