The Ninety-Five Theses denied Rome being the church.
"establishing new denominations" This is incorrect, although in the future there was a new denomination established from this, this was not one of the reforms called for in the ninety-five theses.
"allowing only priests to forgive sins" No, the ninety-five theses were against this.
"building palaces with church funds" No, as I stated above, it was against the Roman church, so this makes no sense.
So that leaves us with:
"banning the sale of indulgences"
The ninety-five theses stated that this was tyranny, indulgences having to be paid to the church to release souls from purgatory, a made-up place that is in-between heaven and this life.
