Answer 1

Answer: (D)

Flagella are filamentous protein structures found in prokaryotes, bacteria, archaea, and eukaryotes, though they are most commonly found in bacteria. They are typically used to propel a cell through liquid medium. But the eukaryotic cell flagella is made up of tubulin protein while the prokaryotic cell flagella is made up of flagellin.

So, the correct option is 'D'.
