c. Customers
Answer: CTR
Explanation:
The abbreviation or short name for these terms should be easy to understand and recognize and should describe the terms adequately. These short names should describe the amount of information which may be derived about the above terms.
Some abbreviation rules that are applied for the giving short names to above mentioned terms/entities are as following:
- First letter of the term should not be skipped. In all the three terms A is the first letter of Authors, P is of Publishers and C is the first letter of Customers so these should not be skipped while creating short names for these terms.
- Eliminating vowels: All the non leading vowels are eliminated from right to left.
In Authors, u and o are eliminated.
In Publishers u, i , e are eliminated.
In Customers, u, o and e are eliminated.
- There is no need to use hyphens, dash, slash or other special characters when giving short names to these terms.
- The short names are not repeatable for another term. This means only one abbreviation for each term.
- Eliminate one of any double consonants.
- Put first letter of the term in first location and last in last location of the term. Just as in Author, A and R are placed at 1st and last position of the short name hence ATR.
