a. 1

b. 2

c. 3

d. 4

b. 2

Explanation:

The mitochondria has 2 membranes namely the outer membrane and the inner membrane, which are separated by an inter membrane space. The outer membrane is selectively permeable to ions and molecules and also holds the whole mitochondria structure. in contrast, the inner membrane is less permeable and it is where electron transport occurs, between protein complexes found within the structure.
