How many of the following do not support 'BIT' data type?

MyISAM, MEMORY, NDB

This question is about data types in MySQL.
MySQL is a popular database system used to store and manage data.
Data types define the kind of information a column can hold, like numbers, text, or dates.
BIT is a special data type that stores a single bit (either 0 or 1).
The question asks about three storage engines in MySQL:
* MyISAM: A fast and reliable storage engine.
* MEMORY: Stores data in RAM for very quick access.
* NDB: A distributed storage engine for managing large datasets across multiple servers.
The correct answer is Option A: 0. This means all three storage engines (MyISAM, MEMORY, and NDB) support the BIT data type.
So, all of them can store data using the BIT data type.
