In the following SQL command "*" stands for? SELECT * FROM person;

Answer: Option A

This question asks about the meaning of the asterisk (*) symbol in a SQL query.
Let's break down the query:

SELECT * FROM person;

* SELECT: This keyword tells the database you want to retrieve data.
* FROM person: This tells the database which table to get the data from (in this case, a table called "person").
* * : This is where the asterisk comes in. It's a wildcard symbol.

So, what does the asterisk mean?
It means you want to retrieve all the columns (data fields) from the "person" table.

Therefore, the correct answer is Option A: Retrieve all data from the table.
