The correct option is
A
Colocasia
Raphides are needle shaped crystals made up of calcium oxalate.
They have sharp ends. They are involved in the defense mechanism for plants against predators.
When tissues with raphides are consumed by predators, the predator's throat can get injured because of the raphide's sharp ends.
Some raphides contain toxins too. Such raphides can inject toxin into the herbivore's skin. Raphides are found in
Colocasia
.
Thus, the correct answer is option A.
