Annelids and arthropods: Bilateral symmetry: Correct. Both phyla exhibit bilateral symmetry.
Sponges: Acoelomates: Correct. Sponges lack a coelom (body cavity).
Coelenterates and Ctenophores: Radial symmetry: Correct. Both phyla exhibit radial symmetry.
Platyhelminthes: Diploblastic organisation: Incorrect. Platyhelminthes (flatworms) are triploblastic, meaning they have three germ layers (ectoderm, mesoderm, and endoderm). Diploblastic organisms only have two germ layers (ectoderm and endoderm).

Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity) 
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
