Question

The Ninety-Five Theses called for many reforms, including

Answer 1

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.

Answer 2

Banning sale of indulgences
