The poster best demonstrates the use of the bandwagon technique by option C. The phrase “Hand washing is IN” means that it is in fashion for people to wash their hands.
Some features of the Bandwagon technique are as follows:
• Bandwagon technique involves trying to persuade everyone that a particular thing is good and therefore everyone should join in or do the same thing as the others.
• This technique basically suggests that if many people are doing the same thing then the rest of the population or group should also join in and do the same thing.
• For example: If everyone is eating the same flavor of ice-cream, others would think that is the most delicious one and they would like to eat the same one too.
• The poster shows many people sneezing and the phrase says spreading germs is out and that hand washing is in, which is trying to indicate that a lot of people are at risk and thus by embracing the culture of hand washing they can safeguard themselves as well as the rest of the population . This will help in reducing the spread of the disease.
