Answer:

C) RNA

Step-by-step explanation:

Spliceosome is a complex machinery that performs splicing (removal of the introns from the primary mRNA transcript) and alternative splicing (re-combination of different exons which increases genetic diversity). Spliceosome is composed of small nuclear RNAs (five of them) and proteins that together make snRNPs-small nuclear ribonucleo proteins.

Spliceosome is a ribozyme, meaning that RNAs inside are capable of catalyzing reactions. Catalyzed reactions by spliceosome are the removal of introns, and the ligation of the exons.
