Take easier of the the two

Stmt II

No info about n .INSUFF

Stmt I

Lets assume that:
The order can be mn(m<n) or nm((m>n)

If its mn then m-1 and n+1 can never be consecutive. Therefore it has to be nm where m-1 (i.e. n) and n+1 (i.e m) are again conseutive satisfying Stmt I

SUFF

Hence A

m-1 and n+1 are consecutive ,

therefore, either (m-1) + 1= (n+1) OR m-1 = (n+1) +1


if (m-1) + 1= (n+1)

m= n+1

therefore, m>n

if m-1 = (n+1) +1

m = n +3

m>n

(A) suff

(B) is insuff
