Answer 1

Answer: (A)

$2033/1023$

Answer 2

Teeth of rabbit are present on both the jaws. They are diphyodont, i.e., only two sets are present throughout life. The first set is known as deciduous or milk dentition. It is lost in youth and replaced in the adult by the permanent dentition which cannot be replaced. Teeth are also heterodont, i.e., they are of different types, incisors, canines, premolars and molars. The dental formula of rabbit is $i \frac{2}{1}, c \frac{0}{0}, pm \frac{3}{2}, m \frac{3}{3} = 28$ or $\frac{2033}{1023} = 28$
