The correct answer is option 1: Asthma patient. While asthma is a respiratory condition, it does not directly affect the eyes or the ability to donate them. Asthma primarily affects the airways and causes difficulty in breathing. Since eye donation does not involve any interference with the respiratory system, asthma patients can still be potential eye donors.

Option 2, AIDS patient, is incorrect. AIDS is a viral infection that weakens the immune system. Due to the risk of transmission of the virus, individuals with AIDS are not eligible to donate any organs, including the eyes.

Option 3, Acute leukaemia patient, is incorrect. Acute leukaemia is a type of cancer that affects the blood and bone marrow. Cancer patients, including those with acute leukaemia, generally cannot donate organs or tissues due to the risk of transmitting cancer cells.

Option 4, Both Asthma and Acute leukaemia patient, is incorrect. As explained earlier, acute leukaemia patients cannot donate eyes. Asthma, on the other hand, does not limit the ability to donate eyes. Therefore, this option is partially incorrect.

In conclusion, the only person from the given options who can still donate eyes is an asthma patient (option 1).
