Let (G, *) be a group such that O(G) = 8, where O(G) denotes the order of the group G. Which of the following is true?
  • a)
    There exists no element a in G such that O(A) = 6.
  • b)
    There exists an element in G such that O(a)= 4.
  • c)
    There exists more than one element a in G such that O(A) = 1
  • d)
    None of these
Correct answer is option 'D'. Can you explain this answer?

Theorem: If a is an art element of G, then. O(A) must divide O(G).
Therefore (A) is false, as O(A) = 6 and 6 doesn’t divide 8.
However the converse of the above theorem need not be true, therefore (B) is false.
(C) says there are at least two elements in G with order 1, however this violates the fact that every group can have only one identity element. So (C) is also wrong. So the appropriate choice is (d).

Explanation:

Given:
- Let (G, *) be a group with O(G) = 8.

Analysis:
- The order of an element 'a' in a group G, denoted by O(a), is defined as the smallest positive integer 'n' such that a^n = e, where e is the identity element of the group.

Option a):
- There could exist an element 'a' in G such that O(a) = 6. It is not contradictory to the given information about the order of the group.

Option b):
- There could exist an element 'a' in G such that O(a) = 4. This is also consistent with the given information about the order of the group.

Option c):
- The order of any element in a group is always greater than or equal to 1. So, there cannot be more than one element with O(a) = 1 in the group.

Conclusion:
- Since both options a) and b) are possible based on the given information, the correct answer is option 'D' (None of these).
