functional dependencies.
A functional dependency which is also commonly known as a
database dependency occurs in a database when info stored in the same database
determines other information stored in the same table. Knowing the value of a

Answer:
B. Which customer most frequently purchases bread.
Explanation:
As per the scenario, the data we are receiving from the sales record of the bakery is :
The date on which the items are sold
Each items name which are sold
The number of each item sold and
The price of each item sold
These data are required to estimate how much the company has earned the profit during a given period of time.
So from the above scenario, there is no data given about the customer i.e customer name, customer number, etc. So there is no chance to track the details of a customer purchase history.
Therefore, the most appropriate answer is option B
