| Question 5 |
Which one of the following options is correct?
| G is always cyclic, but H may not be cyclic. | |
| Both G and H are always cyclic. | |
| G may not be cyclic, but H is always cyclic. | |
| Both G and H may not be cyclic. |
If ‘G’ is a group with sides 6, its subgroups can have orders 1, 2, 3, 6.
(The subgroup order must divide the order of the group)
Given ‘H’ can be 1 to 6, but 4, 5 cannot divide ‘6’.
Then ‘H’ is not a subgroup.
G can be cyclic only if it is abelian. Thus G may or may not be cyclic.
The H can be cyclic only for the divisors of 6 and H cannot be cyclic for any non divisors of 6.
