Assertion (A) : Hemichordat is now placed as separate phylum under nonchordata. Reason (R) : The stomochord of these animals was once believed to be the notochord.

2 Both $\mathrm{A}$ and $\mathrm{R}$ are correct and $\mathrm{R}$ is not 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:
B The stomochord and Notochord are two distinct structure fund in chordates. Stomochord: is present the primitive chordates like hemichordate and located in mouth and intestine and function is supporting the pharyngeal region and aiding in filter feeding. The Notochord is present in chordate and all vertebrates. It is flexible, rod like structure that runs thru dorsal side of the body. Notochord support and provides the basis of muscles attachment. The Notochord it more complex and fundamental structure in chordates white the stomochord is specific to certain group of phylum like hemichor dates.

B Given diagram is belongs to balanoglossus of phylum hemichordata. Their body is a cylindrical like worms and divided into 3 main parts : an anterior part is proboscis, a collor $\&$ a trunk. The function of gill slits in hemichordate is for the movement of water in the mouth.

Explanation:
C The hemichordates are represented by organisms such as the acorn worms and they are solitary worms like organisms with a proboscis and collar. They exhibit bilateral symmetry. - The condition of having similar parts regularly arranged around a central axis.

Larva of balanoglossus is
1 Tadpole

4 Valrus larva
Explanation:
B Balanoglossus belongs to the phylumhemichordata. The animals in hemichordata have a short notochord present in the anterior part of the body. There are two class in the hemichordata known as 'Enteropheusta' and 'Ptetrobranchia'. The larva of the animals of the formal class is called as tornaria. Tornaria larva is the planktonic larva. It is just like bipinnaria larva of star fishes.
