The correct answer is A. Table.
A table is a collection of related records in a database. Each record is a set of data about a single entity, such as a person, product, or order. The data in a table is organized into columns and rows. The columns represent the different attributes of the entity, and the rows represent the individual instances of the entity.
For example, a table of customers might have columns for customer name, address, phone number, and email address. Each row in the table would represent a single customer.
Tables are the basic building blocks of databases. They are used to store data in a structured way that makes it easy to retrieve and analyze.
Option B, database, is a collection of related tables. A database can contain many tables, each of which stores data about a different entity. For example, a database of customers might contain a table of customers, a table of orders, and a table of products.
Option C, file, is a collection of data that is stored on a computer. A file can be a text file, a spreadsheet, a database, or any other type of data.
Option D, none of the above, is incorrect. A collection of related records in a database is known as a table.
