Answer in Python:
<em># Define program constants</em>
PI = 3.14
<em># Welcome the user to our program</em>
print("### Welcome to the Sphere Volume Calculator")
<em># Ask for the Radius (r) input and store it as a float</em>
radius = float(input("Type the Radius of your sphere in meters: "))
<em># Calculate the volume</em>
volume = 4 / 3 * PI * radius ** 3
<em># Print the result</em>
print("Your sphere volume is:", volume, "m³")

Answer:
The correct answer to the following question will be Option C (Data dictionary).
Explanation:
In this question, the option is missing. The option for the given question is given below :
A) Database Management system
B) Database
C) Data dictionary
D) Entity-relationship Diagram
Data Dictionary:
A data dictionary, as described in the IBM Computing Dictionary, is a "git repository of data information such as context, relationships with other records, origin, use, and structure." Oracle describes this as a set of metadata tables. It gives the definition of metadata which is nothing else data about data.
- Option A and Option B do not define metadata that's why this option is not fruitful.
- Option D is the entity-relationship diagram it gives the diagrammatic representation between the entity it does not defines metadata that's why this option is not fruitful.
Hence Option C i. e "Data dictionary" is the correct answer.
The answer to this is c...hope that this helped
