Reason of lung cancer : -Long exposure to fine dust in workplaces can damage the lungs. Fine particles (smaller than 2.5 $\mu m$) reach deep into the alveoli, causing inflammation and fibrosis.
Cement dust contains silica, chromium compounds and other irritants. Workers in cement factories are exposed to heavy dust and have an increased risk of chronic lung diseases and lung cancer.
(Coal mining mainly causes coal workers' pneumoconiosis or black lung, and the link to cancer is weaker.)
So, as per the answer key, the reason of lung cancer among these is the cement factory.
