The correct answer is B. Lenient.
A lenient attitude towards students who are weak in studies is the most appropriate. This is because students who are weak in studies often need more support and encouragement than other students. A lenient attitude can help to create a more positive and supportive learning environment for these students, which can in turn help them to improve their academic performance.
A strict attitude towards students who are weak in studies is likely to be counterproductive. This is because students who are already struggling academically are likely to feel even more stressed and anxious if they are constantly being put under pressure. This can lead to them becoming even more discouraged and less likely to put in the effort to improve their grades.
A liberal attitude towards students who are weak in studies is also likely to be counterproductive. This is because students who are not held accountable for their academic performance are less likely to take their studies seriously. This can lead to them falling even further behind academically.
A lovable attitude towards students who are weak in studies is important, but it is not enough on its own. Students who are weak in studies also need to be given the support and encouragement they need to succeed academically. A lenient attitude can help to create a more positive and supportive learning environment for these students, which can in turn help them to improve their academic performance.
