Solution (By Examveda Team)
This question is about character sets and collations in MySQL.Let's break it down:
* Character set: A character set defines the set of characters that a database can store. Think of it like an alphabet, but for computers. For example, the `latin1` character set includes characters from the English alphabet.
* Collation: A collation is a set of rules that determine how characters are compared and sorted. It defines things like case sensitivity, accent sensitivity, and how characters are ordered (e.g., A-Z or Z-A).
Now, the question asks about the maximum number of collations a character set can have.
The answer is D: More than 1.
Here's why:
A single character set can have multiple collations. This is because a character set can be sorted in different ways (e.g., case-sensitive or case-insensitive, with or without accent sensitivity).
Example: The `latin1` character set has several collations:
* `latin1_swedish_ci`: Case-insensitive, accent-insensitive.
* `latin1_general_cs`: Case-sensitive, accent-sensitive.
So, a character set can have more than one collation to accommodate different sorting and comparison needs.
