Rank fatty acids from most ATP generated to least ATP generated?

I added some letters so it's easier to put them in order. I tried it but got it wrong.

The fatty acids that you have are:
A. saturated, 16 C
B. saturated, 14 C
C. unsaturated, 14 C
D. saturated 13 C
E. saturated 15 C
Beta oxidation of A will yield 8 Acetyl-SCoA + 7 NADH + 7 FADH2.
Beta oxidation of B will yield 7 Acetyl-SCoA + 6 NADH + 6 FADH2
Beta oxidation of C will yield 7 Acetyl-SCoA + 6 NADH + 5 FADH2
Beta oxidation of D will produce 5 Acetyl-CoA, 4 NADH + 4 FADH2 + propionyl-CoA
Beta oxidation of E will produce 6 Acetyl-CoA, 5 NADH +5 FADH2 + propionyl-CoA
The propionyl-CoA will be converted to succinyl-CoA in a set of reactions that consumes 1 ATP. The Succinyl-CoA will be consumed by the remaining part of the CAC, but will produce less ATP than an acetyl CoA.
So, in decreasing ATP order:
A > B > C > E > D
A. saturated, 16 C
B. saturated, 14 C
C. unsaturated, 14 C
D. saturated 13 C
E. saturated 15 C
Beta oxidation of A will yield 8 Acetyl-SCoA + 7 NADH + 7 FADH2.
Beta oxidation of B will yield 7 Acetyl-SCoA + 6 NADH + 6 FADH2
Beta oxidation of C will yield 7 Acetyl-SCoA + 6 NADH + 5 FADH2
Beta oxidation of D will produce 5 Acetyl-CoA, 4 NADH + 4 FADH2 + propionyl-CoA
Beta oxidation of E will produce 6 Acetyl-CoA, 5 NADH +5 FADH2 + propionyl-CoA
The propionyl-CoA will be converted to succinyl-CoA in a set of reactions that consumes 1 ATP. The Succinyl-CoA will be consumed by the remaining part of the CAC, but will produce less ATP than an acetyl CoA.
So, in decreasing ATP order:
A > B > C > E > D

The internet says:
"More C's yield greater ATP per oxidation.
Saturated fats yield greater ATP than unsaturated (double bond) fats"
"More C's yield greater ATP per oxidation.
Saturated fats yield greater ATP than unsaturated (double bond) fats"
