Please see the attachment for the table

Each of the letters in the table above represents one of the numbers 1, 2, or 3, and each of these numbers occurs exactly once in each row and exactly once in each column. What is the value of r?
(1) v + z = 6
(2) s + t + u + x = 6

I think D

Numbers in rows do not equal, numbers in colums do not equal
only 1, 2, 3

(1)
v+z=6
only if v=z=3
Numbers in rows do not equal, numbers in colums do not equal, so r=3
SUFF

(2)
s+t+u+x=6
Numbers in rows do not equal, numbers in colums do not equal
s≠t, u≠x
can be
1+2+1+2=6, r=3
or 2+1+2+1=6, r=3
SUFF

D

OA?

I opt for D as well.

This one is more like a Sudoku puzzle than a DS Q :)
