The correct answer is

1, 2 and 4

Ancylostoma duodenale (hookworm) causes chronic blood loss and iron-deficiency anemia; Ascaris lumbricoides larval lung migration causes Loffler syndrome (pulmonary eosinophilia); Trichinella spiralis causes myositis from larval encystment in muscle. Katayama fever is associated with acute Schistosomiasis, not Loa loa, so pair 3 is incorrect, making 1, 2 and 4 the correct pairs.
