I will go with B. r= 3

Statement 1: V is 3 and z is 3
Statement 2: s + t + u + x = 6
The only value that will satisfy this equation is when
s + t is 3 and u + x is 3.
Since s + t is 3 which means that one of them will be 2 and the other one will be 1, so r has to be 3

v+z=6 => v=3, z=3. This means that s and t cannot be 3 because they are in the same column as v and z respectively. Since one number in the top row has to be a 3, r = 3

Thanks AJB, missed out on the 'same column'
