You have a couple implications here.
You can solve this problem either using the allowed list for a given trunk,
or you can manipulate port parameters so the switch selects according to
your desires.
If there is no constraint on how, and no inclusion like, if port x fails all
vlans need to go over this trunk you could use the allow list for the trunk.
If there are constraints then I would look at using port priority and port
cost. Which would essentially account for a fallback if a port did fail.
As the question is that you posted, I would not read into it too much. As
for load balanance, the key here is odd vlans on one trunk and even on
another. So you should be able to get away with simply using the allow list.
If I encountered this in the lab I would ask the proctor if I need to
account for fallback or if simply having all odd on trunk x and all even on
trunk y meets the critieria.
Hope this adds some help to your situation.

Hi Group,
If we have say VLAN 21-27 and we are asked to load balance all odd
vlans on one trunk and all the even on the other .. do we have to just use 6
VLANs ( i.e 21,23 & 25 on one trunk and 22,24&26 on the other) or do we use
all the 7 ?
I had labbed this and have observed that VLAN 27 will by default be on the
same trunk as the other odd vlans.
regds..
