Select the correct option from the given alternatives. If A = [[1,2],[3,4]] and A(adjA) = kI then the value of k is i]2 ii]− 2 iii]10 iv]− 10

If A=[[1,2],[2,1]] and A(adjA)=k , then the value of k is

If A=[[2,-2],[4,3]] then adjA

if A =[[2,3],[1,4]] then adjA = ?

If A={:[(1,2),(3,4)]:}," then: " adj(adjA)=

A = {:[(1,2),(3,4)]:} and A (adj A) = kI , then the value of 'k' is
