In translation the formation of the initiation complex occurs when:

A. Large and small ribosomal subunits link together, then bind to the mRNA.
B. The small ribosomal subunit holding a meth-initiator tRNA binds to the mRNA, locates initiation codon and then the large ribosomal subunit associates with the complex.
C. Ribosome binds to the start codon of the mRNA and a meth-initiator tRNA enters the ribosome.
D. Meth-initiator tRNA binds to the start codon of mRNA and then associates with ribosome. E. Ribosomal large subunit and mRNA associate, and then bind with ribosomal small subunit, followed by meth-initiator tRNA binding to the ribosome.

The translation is a process which takes place in the cytoplasm of the cell to generate or produce the proteins from the transcribed mRNA form of DNA. The process of translation proceeds in three steps mainly: initiation, elongation and termination.

During the initiation process, the process starts when the small ribosome unit of the ribosome attaches the charged tRNA to itself. They together recognize the 5' cap of the mRNA in eukaryotes or attach to the Shine-Dalgarno sequence in prokaryotes. These after recognizing starts scanning the mRNA in 5' to 3' direction to locate the initiation codon-AUG after which the large subunit of the complex binds. This forms the complete initiation complex

Thus, Option-B is the correct answer.
