Answer:
The word tenderness means soft and a feeling of concern and gentleness. It refers to love and affection and warmth.
Whereas sentiments are known as feelings and emotions that one feels and like to show others.
Tenderness can be used as a sentiment because sentiments can be harsh and they can be soft. Sentiments can be positive and they can be negative.
Tenderness would fall when someone is so soft and bleak of heart that they cry when the other cries and feels what the other is going through, either happy or sad.
The purpose of the advertisements is to sell the products to the customers. Using survey, advertisers develop insight about this. The advertisement does not always provide product details. Indeed, the concept of the product details is the result of the survey, but it does not mean that the concept has to be shown in the advertisement.
Options A and D are very close answers to the question. Catchy slogan does not add exact persuasiveness to the advertisement. Indeed, persuasive advertisement for the product shows the product for the needs of the customers. Therefore, the correct answer is D.
