Answer:
d. A syntax error, if aquarium.db does not already exist on our computer.
Step-by-step explanation:
The SQLite database is a relational database used readily in python backend web frameworks to store and retrieve data. The python packages like the sqlite3 are extensions of python proving its flexibility and power as a multi-purpose programming language.
The sqlite3 package is first installed and imported in the python file and a sqlite connection is made to the database which is automatically saved in the aquarium.db file ( created if it doesn't already exist ).
