Answer: Shift the graph two units down and left one unit.
Step-by-step explanation:
Here the parent function,

When the function is shifted left by a factor a then the new function is,

While when the function is shifted right by a factor A then new function,

Since here the transformed function is, 
Therefore it was obtained by shifting 1 unit towards left,
Now, when the parent function is shifted vertically upward by a factor a,
Then the new function is, 
While, when the parent function is shifted vertically downward by a factor a,
Then the new function is, 
Here, the transformed function is,
,
Therefore, it was obtained by shifting 2 unit downward.
Hence, Third Option is correct.
