Definetly Bradford. If you're sure you want to go to DMU and you get BBC, i'm sure they'll allow one grade under. Putting Wolves are you insurance has no benefit because if you end up getting BBC and both the BBB options reject you - you're pretty much left at the mercy of clearing. It's quite risky putting down the two equal offers because uni's usually only let you in one grade under if they're your firm.
As a side note, just because your family want to stay close, it doesn't mean you should pick your choices to suit them. Of course, they're paying for some of it but it's YOUR 4, possibly, 5 years of life being invested into a university. My parents really wanted me to go to Manchester, because it's near where we live and they can visit frequently - i went against that for independance.
Good luck either way, hope i helped
