In the citric acid cycle, per acetyl-CoA entering the cycle, which set of products is produced?

When one acetyl-CoA goes through one turn of the citric acid cycle, three NADH, one FADH2, and one GTP are produced. The NADH come from three dehydrogenase steps: isocitrate to α-ketoglutarate, α-ketoglutarate to succinyl-CoA, and malate to oxaloacetate. The FADH2 comes from succinate being oxidized to fumarate. The GTP (substrate-level phosphorylation) is generated when succinyl-CoA is converted to succinate. (Two CO2 are also released in this turn, but they aren’t listed in the chosen set.) This combination of products matches the option with 3 NADH, 1 FADH2, and 1 GTP.
