$RuBisCO$ in $C_4$ plants shows minimum oxygenase activity due to

Identify the correct characters of bundle sheath cells in $C_4$ plants from the following list:
$1.$ Thick walls.
$2.$ Intercellular spaces are present.
$3.$ Impervious to gaseous exchange.
$4.$ Contain grana.
$5.$ Contain thylakoids.

Assertion: $C_4$ pathway of $CO_2$ fixation is found in some tropical plants.
Reason: In this pathway,$CO_2$ is fixed by $3C$ compound.

Sugarcane has the highest $CO_2$ fixation capacity among all because it follows:

In $C_4$ plants,the Calvin cycle occurs in:
