Solution

The correct option is B 1 sc RNA + 6 proteins
The signal recognition particle RNA, (also known as 7SL, 6S, ffs, or 4.5S RNA) is part of the signal recognition particle (SRP) ribonucleoprotein complex. It consists of 1 scRNS and 6 proteins. SRP recognizes the signal peptide and binds to the ribosome halting protein synthesis.
So, the correct answer is '1 sc RNA + 6 proteins.'
