1. A
   It initiates the assembly of flagellar basal bodies in non-motile species
2. B
   It provides essential structural proteins for bacterial cell wall synthesis
3. C
   It directly synthesizes ribosomal subunits independent of 70S machinery
4. D
   It confers unique phenotypic characters such as resistance to antibiotics
