both will be trivial subgroup. isint?
Yes both are trivial
Can there be a group with just one element?
Yes a group with only one element is possible
Example {1,*} or {0,+} both are group of one element.

As 29 is a prime number.

The order of subgroups should divide the order of the group from where they are taken.

Now if o(g)=29 then the possible divisors are 29 and 1.

Therefore number of subgroups=2 which are trivial

While number of proper subgroups=zero
