Q 2272112036.     If `vec(a),vec(b)` and `vec(c)` be any three non-coplanar vectors. Then the system `vec(a') , vec(b')` and `vec(c')` which satisfies

`vec(a) * vec(a') = vec(b) * vec(b') = vec(c)* vec(c') =1`

and `vec(a) * vec(b') = vec(a) * vec(c') =vec(b) * vec(a')`

`= vec(b) * vec(c') = vec(c) * vec(a') = vec(c) * vec(b') = 0`

is called the reciprocal system to the vectors `vec(a),vec(b)` and `vec(c)`
The value of ` [ vec(a') vec(b') vec(c') ]^(-1)` is

A

`< [ vec(a)vec(b)vec(c) ]`

B

`= [ vec(a)vec(b)vec(c) ]`

C

`> [ vec(a)vec(b)vec(c) ]`

D

`0`
