Tuberculosis is the correct answer. This is a disease that can spread through the air. Let`s now look at the other options to understand why they do not fit the criteria of being transmitted through the air.

Option 1: Dengue. This is a viral disease transmitted by mosquitoes. It cannot be spread through the air, but rather through the bite of infected mosquitoes.

Option 3: HIV-AIDS. This is a sexually transmitted infection. It is primarily transmitted through sexual contact, sharing needles, or from mother to child during childbirth or breastfeeding. It is not transmitted through the air.

Option 4: Goitre. This is a condition caused by an iodine deficiency. It does not spread from person to person and is not transmitted through the air.

Therefore, the only disease in the list that can spread through the air is tuberculosis. Tuberculosis is a bacterial disease that primarily affects the lungs and can be spread when an infected individual coughs or sneezes, releasing respiratory droplets into the air that can then be inhaled by others.
