Solution

The correct option is B Seven
In the given sequence AUG is the start codon which will initiate the process of translation so it will continue from AUG to CUG because UGA is a stop codon which does not code for any amino acid, other stop codons are UAG & UAA.
So, the correct answer is "Seven".
