Answer:
All options are incorrect.
Explanation:
The teacher wants to continue working, but his state of health is weakened, so he should not ignore their health problems, but seek to treat them with medical care so that their quality of life is good. The teacher does not want to retire, so he should keep working, but he should keep doing his work with the same level of quality. You may be wondering "how will the teacher do quality work without ignoring your health?" This is simple to answer, the teacher should choose a single branch of his profession and work only on it, ie the teacher should choose only to teach or research. This way your workload will be reduced, he will have time to take care of his health and will be able to keep his work with good quality.
