The two most important properties of all matter are:
(a.) the ability to carry an electric current well and to hold electric charge
(b.) taking up space and having mass
(c.) being brittle and hard
(d.) being malleable and ductile

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
