Given matrices g and h below, which statement is true?

g= 7 5
4 3

h= -6 -5
-4 -2

a.) matrices g and h are not inverses of each other because g + h does not equal i.

b.) matrices g and h are not inverses of each other because gh does not equal i.

c.) matrices g and h are inverses of each other because gh = i.

e.) matrices g and h are inverses of each other because g + h = i.
