If \ov a, \ov b,\ov c, & \ov a' , \ov b', \ov c' are reciprocal system of vectors then \ov a'\times\ov b'+\ov b'\times\ov c'+\ov c'\times\ov a'=

Correct Answer is : a+b+c[a b c]

{\ov a+\ov b-\ov c }/[{\ov a \ov b \ov c} ]

{\ov a-\ov b+\ov c }/[\ov a \ov b \ov c ]

{\ov a+\ov b+\ov c }/[\ov a \ov b \ov c ]

{-\ov a+\ov b+\ov c }/[\ov a \ov b \ov c ]
