The correct answer is D. Performs his responsibility honestly.
A teacher can get an important place in society if he performs his responsibility honestly. This means that he should be fair and impartial in his teaching, and should not discriminate against any student. He should also be respectful of his students and their parents, and should be willing to help them learn.
The other options are not as important as performing his responsibility honestly. Being an active member of the political party in power or being a scholar and in power are not necessary for a teacher to be respected and valued in society. Participating actively in social activities can be a good thing, but it is not essential for a teacher to be successful.
In conclusion, the most important thing for a teacher to do is to perform his responsibility honestly. This means that he should be fair and impartial in his teaching, and should not discriminate against any student. He should also be respectful of his students and their parents, and should be willing to help them learn.
