If the dot-product of two vectors  "a"  and  "b" equals 6, then the dot-product of the vectors  "b"  and  "a"  

(in this order) has the same value and must be equal to 6.



Since the given list of options does not contain this value 6,  this list is DEFECTIVE.



The answer is "no one of the listed option works".
