Read the given paragraph carefully and decide which of the conclusions given in the options logically follows from the paragraph.
In a TV show, a famous nutritionist said that among different items offered for breakfast, muesli has more nutritional value than regular cereals. He also said that oatmeal is healthier than bread. But a recent commercial of a cereal company says that cereals like cornflakes are richer in nutrition than plain muesli. The consumers are posting severe criticism on social media and on the company website about the misinformation in the advertisement.

Lets check by options;

Option (a); The nutritionist has deliberately made that comment to generate negative sentiments against the cereal company. (Does not follow)

There is no evidence in the paragraph suggesting that the nutritionist intentionally wanted to damage the company's reputation.

Option (b); The nutritionist has high credibility, and people believe his/her words against that of the famous cereal company. (Follows)

Since consumers are criticizing the cereal company's claim, it implies they are trusting the nutritionist's statement more than the advertisement.

Option (c); The cereal company had done the advertisement based on outdated research, and the misinformation was unintentional. (Does not follow)

The paragraph does not mention outdated research or whether the misinformation was intentional or accidental.

Option (d); Social media sites are increasingly becoming popular among customers as complaint portals. (Does not follow)

While customers are complaining on social media, the paragraph does not make a general statement about the increasing use of social media as a complaint portal.

So, option (b) is follows.

Thus, the correct answer is (b).
