Answer 1

Answer: (A), (C)

The correct options are
A inner
C cristae

Mitochondria are made of two membranes. The outer membrane covers the organelle and protects it. The inner membrane folds over many times and creates a layered structures called cristae. The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle.
