Answer:
B) 6th string, open
Explanation:
When you read a guitar tab, the bottom line is the top string (E) and as you progress through the strings, you go higher on the tab
so top to bottom on the tab lines it would be
EADGBE
and from the bottom to the top of the lines on the tab would be
EBGDAE
So the top string right there is the high E
the number on the line shows you what fret you place your finger on
since the number is a 0, you don't place your finger anywhere and just pluck the open 6th string.
Hope this helps : )
