@All.
According to me, the difference between the 2 digits.
So, 10-3=7 and 101-10=91.
Now, the pattern I used was to multiply 7 with 3 and with 10. I got the answer 101. So, doing the same; I multiplied 91 by 10 and 101. I got 10101 from that method.
Now tell me, which one is correct?

10 - 3 = 7, 10 + 3 = 13, 13 * 7 = 91.
91 + 10 = 101,
So, by this logic.
101 - 10 = 91, 101 + 10 = 111, 111 * 91 = 10101.
10101 + 101 = 10202.
91 + 10 = 101,
So, by this logic.
101 - 10 = 91, 101 + 10 = 111, 111 * 91 = 10101.
10101 + 101 = 10202.

Because it is the pattern.
As when 3 is multiplied by 3 it gives 9.
And when 9 is added by 1 it gives 10 and so on the series continues.

Because that is the pattern.
i.e 3 when multiplied by 3 gives = 9.
And when 1 is added it gives 10 and so on.
i.e 3 when multiplied by 3 gives = 9.
And when 1 is added it gives 10 and so on.

Ans: C.
3 * 3 = 9 + 1 = 10.
10 * 10 = 100 + 1 = 101.
101 * 101 = 10201 + 1 = 10202.
3 * 3 = 9 + 1 = 10.
10 * 10 = 100 + 1 = 101.
101 * 101 = 10201 + 1 = 10202.

3 x 3 = 9 + 1 = 10.
10 X 10 = 100 + 1 = 101.
101 X 101 = 10201 + 1 = 10202.
3 x 3 = 9 + 1 = 10.
10 X 10 = 100 + 1 = 101.
101 X 101 = 10201 + 1 = 10202.

(3)^2+1 = 9+1 = 10,
(10)^2+1 = 100+1 = 101,
(101)^2+1 = 10201+1 = 10202.
(10)^2+1 = 100+1 = 101,
(101)^2+1 = 10201+1 = 10202.
