Electron transport cannot proceed if protons cannot be pumped across the inner membrane. Protons cannot be pumped unless the available energy to move them out of the matrix exceeds the required amount plus what energy is lost to heat.

No, the Krebs cycle requires oxygen as the final electron acceptor in the electron transport chain to function properly. Without oxygen, the electron transport chain cannot proceed, leading to a buildup of molecules that inhibit the Krebs cycle. This can result in the Krebs cycle slowing down or ceasing altogether.
In the Krebs cycle NAD+ is reduced to NADH. This is one of the electron carriers. Also FAD is reduced to FADH2 which is the other electron carrier produced during the Krebs cycle.

The electron transport chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.
Yes, the electron transport chain can occur without the Krebs cycle. The electron transport chain generates ATP by transferring electrons through a series of protein complexes in the inner mitochondrial membrane, regardless of whether the electrons come from the Krebs cycle or other sources.
the answer they put is wrong
The first stage is the break down of glucose. The second stage is the Krebs Cycle which breaks down the pyruvic acid. The third stage is the electron transport system which occurs in O2 and in the mitochondria.

The main electron carriers of the Krebs cycle are NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). These molecules accept electrons and transport them to the electron transport chain for ATP production.
