Statement 1: it implies that n>0 (as mod cannot be negative) and "m" can be m>0 or m<0
if m>0, then m=n, so mn = nn
if m<0, then m=-n, so mn<nn (as "mn" will be negative & "nn" will be positive)
In either case "mn" will not be greater than "nn". So a definite NO. Hence sufficient
Statement 2: we don't know whether "m" & "n" are positive or negative.
if n>0, then multiplying both sides of the inequality m<n by "n" will give us mn<nn, but
if n<0, then multiplying both sides of the inequality m<n by "n" will yield mn>nn. Hence insufficient

Statement 1. |m| = n. Now m and n are non-zero, so |m| Must be positive. This means n is definitely positive, and m could be either positive or negative (but absolute values of m and n are equal)
Now if m is also positive, then m=n, and thus m*n = n*n.
And if m is negative, then m*n < n*n
So we can conclude that m*n will be either equal to or less than n*n. It could never be greater than n*n.
So this gives NO as an answer to the question asked. Thus Sufficient.
Statement 2. m < n
Take a case where m=-2, n = 1. Here m*n < n*n
Take another case where m=-2, n=-1. Here m*n > n*n.
So we cannot conclude. Insufficient.
Hence A answer
