Apply the indicated operation to the matrix.
will mark brainliest, anyone pls?

Answer:
your answer is D.
-3 -2 -1
0 3 6
Step-by-step explanation:
the number on the left of the indicated operation is the original set
the number '3' next to R shows that you need to multiply certain numbers by 3
the subscript on the R's shows which row the multiplication needs to be done on...
in this case the row is 2, and you need to multiply it by 3
so the first row will stay the same: -3 -2 -1
but the second row will change to: 0 3 6
