    Solution:

    Concept- To find the cube root, form a group of numbers with three groups starting on the right, as shown below. , Apply this concept to find the unit digit of the cube root given the number.
    It forms three groups starting with the rightmost number 4913. i.e, Next, the two groups are 4 and 913.
    Where 4 is only 1 digit and 913 is 3 digits.
    Now, Take 913
    Unit place digit number = 3.
    Therefore, the required cube root squared is 7. Then take the other group 4.
     As we know that 3
    Where the minimum number between 1 and 2 is 1.
    Therefore, use 1 as the tense.  Hence, the correct answer is option (1).
