Which pair is wrong : -Maize is a $C_4$ plant (like sugarcane and sorghum), not a $C_3$ plant. So '$C_3$ – Maize' is wrong.
$C_4$ plants have Kranz anatomy (bundle sheath cells with chloroplasts around the vascular bundles); correct.
The first stable product of the Calvin cycle is PGA; correct.
The first stable product of the Hatch and Slack ($C_4$) pathway is oxaloacetic acid (OAA); correct.
So the wrong pair is $C_3$ – Maize.
