• Influenza, commonly called 'the flu' is an illness caused by RNA viruses of the family Orthomyxoviridae. For example, Myxovirus influenzae.
  
• The most common symptoms include high fever, runny nose, sore throat, muscle pains, headache, coughing, sneezing, and feeling tired.
• Hence Myxovirus influenzae is the causative organism of influenza.
• So, the correct answer is 'Myxovirus influenzae'.

• Influenza is a viral disease. Influenza virus is of three types, viz; type A, type B and type C. This virus spread even is short distances causing flu-like conditions, fever, runny nose, headache, muscle pain, coughing, etc. 
  
• Typhoid is a disease caused by the bacteria named Salmonella typhi. 
• Dysentery is a gastroenteritis disorder causing diarrhoea. This disorder can be caused by bacteria, viruses, protozoans or parasites. 
• Cholera is caused by the bacteria named Vibrio cholerae. 
So, the correct answer is option B.

Causative agent of cholera is Vibrio cholerae. Vibrio cholerae is a bacterium. 
Tuberculosis is caused by bacteria, Mycobacterium tuberculosis.
Anthrax is caused by bacteria Bacillus anthracis. 
Influenza is caused by influenza virus. 

Pandemic is an epidemic of infectious disease that spreads through human populations across a large region; for instance multiple continents, or even worldwide. The World Health Organization (WHO) has a six-stage classification that describes the process by which a novel influenza virus moves from the first few infections in humans through to a pandemic. This starts with the virus mostly infecting animals, with a few cases where animals infect people, then moves through the stage where the virus begins to spread directly between people and ends with a pandemic when infections from the new virus have spread worldwide and it will be out of control until we stop it. A disease or condition is not a pandemic merely because it is widespread or kills many people; it must also be infectious. 

Use of aspirin during dengue fever is not recommended owing to increased bleeding tendency. Aspirin has an antiplatelet effect by inhibiting the production of thromboxane, which under normal circumstances binds platelet molecules together to create a patch over damage of the walls within blood vessels. Hence drugs such as aspirin and ibuprofen should be avoided as they may increase the risk of haemorrhage. 

Bacillus haemophilus or Bacillus influenzae is a Gram-negative, facultatively anaerobic bacteria that causes influenza disease. It was first described by Richard Pfeiffer during an influenza pandemic. It is usually present in the upper respiratory tract and causes otitis media, epiglottitis, and meningitis.

The organisms or agents which are responsible for the development of a disease or any infection is known as a pathogen. The ability of the organism to cause disease is pathogenicity. The microbes like the virsues, bacteria, and fungi are known as the pathogens which cause a certain type of infection. 

Cholera is caused by the bacterium Vibrio cholerae. This bacteria is usually found in food or water contaminated by feces of an infected person. This is most likely to happen when sewage water mixes with a source of drinking water. Drinking water after boiling helps to prevent this infection. Thus the correct answer is option B.

Pollutants are the harmful oxides or chemicals which degrade the quality of the environment and causes pollution. 

Rabies is an overwhelming encephalomyelitis and includes severe headache and high fever with excitement and depression. This disease occurs by a virus called Rhabdovirus.
