Read the passage and answer the following questions:

Polio was an epidemic in India in the 1970s. The government tried various ways to curb it, but the results were not impressive. Then Amitabh Bacchan was roped in to be the face of the Pulse Polio Campaign in India. The slogan of polio eradication campaign was "DO BOOND ZINDAGI KE" (Two drops of Life). He educated people on the various advantages of polio vaccination and appealed to them to actively participate in the drive. This brought positive change in people's attitude towards the polio vaccine. After that, Indians took the campaign seriously and actively participated in the polio vaccination drive. Due to the effectiveness of the drive, India has become a polio-free country. Till date, the people in India relate the voice of Amitabh Bachchan to the polio eradication campaign.

What according to you Amitabh Bachchan had, that led to a change in people's attitude towards the campaign?

Credibility and attractiveness

The correct answer is Option (2) → Credibility and attractiveness

In the context of the Pulse Polio Campaign:

• Amitabh Bachchan is a highly respected and trusted public figure in India — this gave him credibility.

• His popularity, public image, and influence made him attractive to the masses in terms of communication effectiveness, not just physical appearance.

These qualities helped him influence public opinion and bring about a positive change in people's attitude toward polio vaccination.

"Source characteristics : Source credibility and attractiveness are two features that affect attitude change. Attitudes are more likely to change when the message comes from a highly credible source rather than from a low-credible source. For example, adults who are planning to buy a laptop are more convinced by a computer engineer who points out the special features of a particular brand of laptop, than they would be by a schoolchild who might give the same information. But, if the buyers are themselves schoolchildren, they may be convinced more by another schoolchild advertising a laptop than they would be by a professional giving the same information (see Figure 6.1). In the case of some products such as cars, sales may increase if they are publicised, not necessarily by experts, but by popular public figures."
