Weird Join Delete

This confused me for a few minutes today and I wanted to share to help avoid further confusion.

 

The specific code was this:


DELETE t2
FROM [dbo].[Table1] t1
INNER JOIN [dbo].[Table2] t2 on t1.favColor = t2.id;

Names have been changed to protect the innocent.

 

In the above delete statement which table will have rows deleted from it?

A: Table1

B: Table2

C: Both Table1 and Table2

D: Neither Table1 and Table2
