Answer Details
The activity that improves the appearance of a product and aims to protect it is "packaging."
Packaging refers to the process of enclosing a product in a container, wrapper, or other material for the purposes of protection, storage, distribution, and display. Packaging can take many forms, from simple plastic bags to elaborate boxes and displays.
One of the primary functions of packaging is to protect the product from damage or contamination during storage and transportation. This can include protection from moisture, dust, and other environmental factors that could damage the product. Additionally, packaging can also protect the product from tampering or theft.
Another important function of packaging is to improve the appearance of the product. Packaging can be designed to attract attention, communicate information about the product, and create a favorable impression on the customer. This can include the use of graphics, colors, and other design elements to create a distinctive and appealing visual identity for the product.
The other options listed - advertising, grading, and labelling - are all important activities in the marketing and distribution of products, but they do not specifically relate to the physical protection and appearance of the product, which is the main focus of packaging.
