Vedclass · Answer

(B) $Oryctolagus$ $cuniculus$ (rabbit) is a representative of class $Mammalia$. $1.$ Dentition in all mammals is heterodont (i.e.,presence of dissimilar types of teeth). Thus,statement $I$ is true. $2.$ Canines are completely absent in rabbits,not just poorly developed. Thus,statement $II$ is false. $3.$ Incisors in rabbits are well-developed,sharp,and chisel-like,used for gnawing. Thus,statement $III$ is false. $4.$ Rabbits are herbivorous,and due to the absence of canines,a gap exists between the incisors and premolars,known as a diastema. Thus,statement $IV$ is true. $5.$ The dental formula of a rabbit is $I \frac{2}{1}, C \frac{0}{0}, P m \frac{3}{2}, M \frac{3}{3}$,which gives a total of $28$ teeth. Thus,statement $V$ is true. Therefore,statements $I, IV,$ and $V$ are correct.
