Options

B proteins & mRNA
C proteins & rRNA
Correct Answer
D lipids & proteins
Correct Answer

Option C is the correct answer.

Detailed Explanation

Ribosomes are complex molecular machines composed of ribosomal RNA (rRNA) and ribosomal proteins. rRNA provides the structural scaffold and catalytic activity for protein synthesis, while proteins stabilize the structure. mRNA carries the genetic code but is not a structural part of the ribosome.

Hint

The 'r' in rRNA stands for ribosomal – it's a key structural and functional component.
