$(C)$ The net gain of $ATP$ during aerobic respiration is calculated as follows:$1$. Glycolysis produces $2$ $ATP$ and $2 NADH + H^+$.$2$. Pyruvate oxidation (Link reaction) produces $2 NADH + H^+$.$3$. Krebs' cycle produces $2$ $GTP$ (equivalent to $2$ $ATP$), $6 NADH + H^+$, and $2 FADH_2$.$4$. In the Electron Transport System $(ETS)$, each $NADH + H^+$ typically yields $3$ $ATP$ and each $FADH_2$ yields $2$ $ATP$.Total $ATP$ calculation: $2$ ($ATP$ from glycolysis) + $2$ ($GTP$ from Krebs' cycle) + $10 NADH + H^+$ ($2$ from glycolysis + $2$ from link reaction + $6$ from Krebs' cycle) $	imes 3$ $ATP$ = $30$ $ATP$ + $2 FADH_2$ $	imes 2$ $ATP$ = $4$ $ATP$.Total = $2 + 2 + 30 + 4 = 38$ $ATP$ (in prokaryotes) or $36$ $ATP$ (in eukaryotes due to the shuttle cost of $2$ $ATP$).Given the options, $36$ is the standard accepted value for eukaryotic aerobic respiration.

Stages	$ATP$ produced through $ETS$
$A$. Glycolysis	$1$. $6$
$B$. Formation of Acetyl $CoA$ from Pyruvic acid	$2$. $3$
$C$. Kreb's cycle	$3$. $24$

$1$. Succinic acid	$p$. $12$ $ATP$
$2$. Citric acid	$q$. $15$ $ATP$
$3$. Pyruvate	$r$. $9$ $ATP$
$4$. $\alpha$-ketoglutaric acid	$s$. $5$ $ATP$
