Final answer:
The SELECT statement is the command that represents the R (Read) in CRUD within the context of SQL, used to retrieve data from a database.
Step-by-step explanation:
The command that represents the R (Read) in CRUD operations usually varies depending on the programming language or the data management system in use. However, in the context of SQL, which is commonly used to interact with databases, the SELECT statement is used to read or retrieve data from a database. It allows you to specify the columns of data you want to retrieve, as well as other conditions through clauses like WHERE, which can filter the data you want to read.
