The process that is taking place in this diagram is DNA replication where the red part of C and D are the primers. These primers are short segment or sequence of RNA that are complementary to the single stranded DNA template. These primers facilitate the elongation process of the DNA replication and after this process, these primers are removed by an enzyme called 5' to 3' exonuclease. These primers are produced by a RNA polymerase known as primase.
Hence, the correct option is (c) Primase.
Options (a) and (b) are incorrect because these enzymes do not produce the primer (red part).
Option (d) is incorrect because primer is repesented by the red part and it is synthesized by the primase.
