B - Incomplete double circulation is seen in Amphibian and Reptiles. - The amphibian have 3-chambered heart with 2 auricles and 1 ventricle. - Normally oxygenated blood gets circulated all over the body and deoxygenated blood is carried back to heart. - However deoxygenated blood can also be stunted to body and oxygenated blood cab be shunted back to lungs. - Bird and mammals are worm-blooded animal have 4chamber heart that separate oxygenated and deoxygenated blood.

Assertion (A): Amphibians remained as imperfect group Reason (R) : Although, Amphibians invaded land, they could not adapt completely to terrestrial life.
1 Both $\mathrm{A}$ and $\mathrm{R}$ are true and $\mathrm{R}$ is the correct explanation of $A$.
2 Both $\mathrm{A}$ and $\mathrm{R}$ are true and $\mathrm{R}$ is not the correct explanation of $\mathrm{A}$
3 A is true and $\mathrm{R}$ is wrong
4 A is wrong and $\mathrm{R}$ is true
Explanation:
A Amphibiane remained as imperfect group because they live on both land and water. Head is clearly distinct but neck and tail may be present or absent hence body is mainly consist of two part (i) Hand (ii) Trunk Exo skeleton is absent and digits without claws the teeth are small and homodantous tongue is bifid toward the anterior end. Alimentary cannel terminates into cloaca . although, Amphibian invaded land, they could not adapt completely to terrestrial life because fertilization is external in presence to water. The development is direct and the larva is generally fad pole larva.

Assertion (A) : Monkey is the reservoir host of malarial parasite Reason (R) : Malaria is transmitted by monkey bite
1 both $\mathrm{A}$ and $\mathrm{R}$ are true and $\mathrm{R}$ is the correct explanation of $\mathrm{A}$
2 both $\mathrm{A}$ and $\mathrm{R}$ are true but $\mathrm{R}$ is not the correct explanations of $\mathrm{A}$
3 A is true and $R$ is false
4 A is wrong and $\mathrm{R}$ is true
Explanation:
C Monkey is the reservoir host of malarial parasite because some malarial parasite like P.knowlesi is cause malaria in monkey, and it develop in to monkey body and transmitted by mosquito. Mosquito (Anapheles hackeri) is the vector of $\mathrm{P}$. Knowlesi. Many life stage found in monkey such as sporozoits cryptozoite, crytometazoites, schizotstage metacryptozoite, tropchoite, signet ring stage and micro and mega gameto cyte.
