Explanation:
I'll assume the question is about the use of constants in QBasic because consonants do not have any special function or usage in QBasic.
In simple terms: In QBasic, constants are used to represent elements that do not change in value during program execution.
Take for instance, you intend to use 
in your program.
Its value is 
So, 3.142 will always be a constant in your program. One of the ways it can be used in a program is:
10 LET PI = 3.142
<em>The above represents a numeric constant. QBasic also have string constants.</em>
Answer: Function
Explanation: <em>"Function is a criterion that is met when the part performs its stated purpose effectively and reliably. In an electronics product, for example, function can depend on the solid-state components used, the software or firmware, and quite often on the features of the electronics enclosure selected. Poorly placed or sized ports and misleading or missing labeling are two of the most common ways in which an enclosure can fail the function criterion."</em>

Answer:
D) use SQL or graphical tools to query the database
Explanation:
To query the database using SQL or graphical tools will help Howie to retrieve bulk of records from the database according to his requirements and it will help to understand and work with the data in a better way than using the data in raw form.
SQL is a language of database used to manipulate and manage the data in the relational database and to query the database.
It is an easy and faster way to query using SQL or graphical tools because no coding is required here.
Different graphical tools are used to present the data in the database in a way that can be easily understood by a person. Different interfaces are provided to visualize the database tables or schema diagrammatically e.g in the form of graphs etc. Different views of the database can be provided to different users according to their requirement and what information they required to be presented.
