Explanation:

Box 1: Yes
Tables are database objects that contain all the data in a database. In tables, data is logically organized in a row-and-column format similar to a spreadsheet. Each row represents a unique record, and each column represents a field in the record.
Box 2: No
An index is an on-disk structure associated with a table or view that speeds retrieval of rows from the table or view.
Box 3: Yes
A view is a virtual table whose cont ents are defined by a query. Like a table, a view consists of a set of named columns and rows of data.
