Assertion (A): Adult gastropods are asymmetrical though there are included in phylum Mollusca. Reason (R): Symmetry of organism is determined in early developmental stages but not in adults.
1 Both $\mathrm{A}$ and $\mathrm{R}$ are correct and $\mathrm{R}$ is the correct explanation of $\mathrm{A}$.
2 Both $\mathrm{A}$ and $\mathrm{R}$ are correct but $\mathrm{R}$ is not the correct explanation of A.
3 $\mathrm{A}$ is correct but $\mathrm{R}$ is incorrect.
4 $\mathrm{A}$ is incorrect but $\mathrm{R}$ is correct
Explanation:
C Adult gastropoda, which are a class of mollusks often exhibit asymmetry in their body structure this characteristic is most prominent in their shells which are usually cold and spiral-shaped the coiling of the shell creates an asymmetrical arrangement, where one side body is larger and more developed than other. This asymmetry is defining feature of astropods and can very in degree across different species.

Which of the following belongs to the classGastropoda?
1 Clam
2 Cuttle fish
3 Snail
4 Mussel
Explanation:
C Cephalopods are group of molluscs that include the pearly chambered Nautilus, octopus and the squids. Snail belongs to the class Gastropoda. Snail is an amphibious mollusc commonly found in ponds, rivers and rice fields. They are herbivorous animal feed mainly on grasses and phytoplankton. The class Gastropoda (in phylum Mollusca) includes the groups pertaining to snails and slugs. The majority of gastropods have a single, usually spirally, coiled shell into which the body can be withdrawn. - Gastropoda is the largest class of molluscs comprising over $80 \%$ of all molluscs.
