ALL catalytsts:
1.) are used up in the coarse of the reaction
2.) lower activation energy
3.) are very specific on which kinds of reaction their catalyze

Yes, you're correct. ALL catalysts lower activation energy.

 Catalysts do not get used up in the course of a chemical reaction. They remain the same.
They are not specific, perse, in the kinds of reactions they catalyse. Peptidases for example, break different peptide bonds. Some are non-restrictive in their amino cleavages.
Some enzymes, eg, nickel, platinum can operate at high temperatures. This flaws the 4th answer option, too.
