Solution
The correct option is B Diatom
- Diatoms are the group of microscopic protists.
- These are the unicellular protists which are made up of many vesicles which are arranged compactly composed of silica.
- The vesicles are arranged to form plate-like structures called frustules which overlap each other.
- This gives the diatoms the structure like a soap case.
Thus, the correct answer is option D.
