What is the order of the product `[x" "y" "z][{:(a,h,g),(h,b,f),(g,f,c):}][{:(x),(y),(z):}]`?

Options

A. `3 xx 1`
B. `1 xx 1`
C. `1 xx 3`
D. `3 xx 3`

Answer

B

Explanation

Given `[x" "y" "z][{:(a,h,g),(h,b,f),(g,f,c):}][{:(x),(y),(z):}]`
Consider `[x" "y" "z]_(1xx3)[{:(a,g,g),(h,b,f),(g,f,c):}]_(3xx3)`
`rArr` order of product `= 1 xx 3`
Now, order of product `= 1 xx 3` and order of `[{:(x),(y),(z):}]=3 xx 1`
`therefore` Required order `= 1 xx 1`
