I guess you already have 3 answers, but 'randomly pick from A B and C' is not at all a clear definition of what you want. There are numerous different interpretations of what that means!

m=[A ; B ;C]
m(randi(3),:)

This picks randomly a column from m, but not randomly from A, B and C.

A = [0,0,1]; B=[0,1,0]; C=[1,0,0];
X = [A; B; C];
x = X(sub2ind(size(X), 1:3, randi(3, [1, 3])))

A=[0,0,1]
B=[0,1,0]
C=[1,0,0]
R = [A(randi(3)), B(randi(3)), C(randi(3))]
