{'leprosy': [0, 1, 0, 1], 'hemophilia': [0, 1, 0, 0], 'syphilis': [0, 0, 1, 1], 'sets': [4, 3, 5, 2], 'diphtheria': [5, 1, 4, 3], 'polio': [3, 0, 0, 0], 'pneumonia': [3, 0, 0, 0], 'plague': [1, 0, 0, 0], 'aids': [4, 0, 1, 3], 'bacterial': [2, 1, 0, 0], 'gonorrhoea': [0, 1, 0, 0], 'sickle cell anaemia': [0, 1, 1, 0], 'hereditary': [1, 1, 0, 1], 'colour blindness': [2, 0, 1, 0]}

Option 1: Diphtheria, Pneumonia and Leprosy are not hereditary diseases. They are infectious diseases caused by bacteria, not passed down through generations.

Option 2: While Syphilis and Gonorrhoea are indeed bacterial infections, AIDS is caused by the human immunodeficiency virus (HIV), not by bacteria. Therefore, this set is not entirely correctly matched.

Option 3: Colour blindness, Hemophilia and Sickle cell anaemia are all considered sex linked diseases. They are caused by mutations in genes that are located on the sex chromosomes. In males, who only have one X chromosome, these disorders are more common as they don`t have a second X chromosome to mask the affected gene.

Option 4: Polio and Japanese B encephalitis are viral diseases, but Plague is a bacterial disease caused by Yersinia pestis. Therefore, this set is also not correctly matched.

Therefore, the correct answer is Option 3.
