Is it A?

Let say numbers be 10w+x and 10c+x

so after mutlpying we can have 100wc+10(w+c)x+x^2

Now since it 3 digit number so wc can be equal to less than 9.

wc can be if each digit is 3 and 3. against the question stem.

Other possibilities are (2, 3) and (2,4). (2,3) will fit the bill when x=4

With all these number 3 digit number will be 666.
