Question #1757c

Answer 1

You should get B) `(n-1)xx(n-1)` matrix.

Explanation:

From what I understood about the question I tried with a practical approach:
Given `A=` `((1,2,3,4),(1,2,3,4),(1,2,3,4),(1,2,3,4))` order `n=4`
deleting, say, the fourth row and column we get:
`B=` `((1,2,3),(1,2,3),(1,2,3))` of order `n-1=3`

...I think!
