**Hint:**In this problem, we have to find the possible one’s digit of the square root of 9998001 from the give to options. To solve this problem, we have to take the digit at the unit place to check for its square. We should know that when the digit at the unit place is 1, then 1 at unit digit can only be obtained from \[{{1}^{2}}\]= 1 or \[{{9}^{2}}\]= 81.

**Complete step by step answer:**

We know that the given square root number is 998001.

Now we have to find the possible one’s digit of the square root of 9998001 from the give to options

1) 2 or 4

2) 1 or 9

We already know that when the digit at the unit place is 1, then 1 at unit digit can only be obtained from \[{{1}^{2}}\]= 1 or \[{{9}^{2}}\]= 81.

We can now analyse the given number to check for the above condition to be satisfied,

Hence, the square root of 998001 will either have 1 or 9 at its unit place.

**So, the correct answer is “Option 2”.**

**Note:**Students make mistakes while finding the number one in the united place. We should always remember that when the digit at the unit place is 1, then 1 at unit digit can only be obtained from \[{{1}^{2}}\]= 1 or \[{{9}^{2}}\]= 81. We should also know where the unit place is in the given numbers to solve these types of problems.
