GTPase activity is involved in the regulation of signal transduction because it
A) phosphorylates protein kinases.
B) increases the available concentration of phosphate
C) converts cGMP to GTP
D) hydrolyzes GTP binding to G protein
E) decreases the amount of G protein in the membrane

if you don't have a clue, how about reading your textbook?
If you lost your textbook you can use google and wikipedia:
function of GTPase.:
The hydrolysis of the γ phosphate of GTP into guanosine diphosphate (GDP) and Pi, inorganic phosphate,
So it you know now that a GTPase hydrolysis GTP into GDP and P, could a) be possibly true? Go through the options and you will find that one of the options will actually exactly tell you what a GTPase does.
