The given vectors are
and 
Two vectors are said to be orthogonal if they are perpendicular to each other. i.e. the dot product of the two vectors is zero.
Let us consider the dot product of the vectors
which is not equal to zero. Hence, the given vectors are not orthogonal.
Two vectors are said to be parallel if one vector is a scalar multiple of the other vector.
Here we can observe that the from the given vectors, one vector can not be expressed as the scalar multiple of the other vector.
Hence, the given vectors are neither parallel nor orthogonal.
if ACE line is linear so you can say BCA angle plus BCE equal to 180 degree
Im not sure what the answer is sorry, have a nice day!
