Question

vector(a,b,c) will be coplanar, if

Answer 1

vectors are coplanar as their scalar triple product is zero. Example 3. Checkwhether the vectors are collinear a = {1; 1; 1}, b = {1; 2; 0}, c = {0; -1; 1}, d = {3; 3; 3}. Since there are two non-zero row, then among the given vectors only two linearly independent vectors.
