Which clause is used to "Modify the existing field of the table"?

Solution (By Examveda Team)

This question asks about the MySQL command that lets you change existing information within a table.
Here's how to break it down:
* ALTER: This command is used to make big changes to a table, like adding new columns, dropping old ones, or renaming the table itself.
* FROM: This clause is used in a SELECT statement to specify which table you want to retrieve data from.
* SELECT: This command is used to retrieve data from a table.
* MODIFY: This is the key! The MODIFY clause is specifically designed to change existing columns within your table. You can use it to change a column's data type, its default value, or even rename it.
Therefore, the correct answer is Option D: MODIFY
