can't figure out which answer is wrong, please explain

Map Sapling Learning The electron transport chain (ETC), or respiratory chain, is linked to proton movement and ATP synthesis. Select the statements that accurately describe the electron transport chain Choose all that apply. Electron carriers are organized into four complexes of proteins and prosthetic groups. Electron carriers in the mitochondrial matrix include one (coenzyme Q), FMN, and cytochrome c. Electrons generated by the citric acid cycle in the mitochondrial matrix enter the ETC. The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. The reactions of the ETC take place in the outer membrane of mitochondria. Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer Electron transfer in the ETC is coupled to proton transfer from the matrix to the intermembrane space. One of your answers is incorrect. Keep in mind that electron carriers undergo oxidation and reduction. Consider the location of these reactions in the ETC.

Explanation / Answer

Fifth option is wrong and remaining all correct. It is because the electrons transport chain complexes are present in inner mitochondrial membrane.
