Polysome is formed by several ribosomes attached to a single mRNA. Polyribosomes or polysomes also known as ergosomes are a cluster of ribosomes, bound to a mRNA molecule. Polysomes are functional unit of protein synthesis. During the elongation phase,  polysomes  are  formed when large clusters of 10 to 100 ribosomes and elongation factor synthesize the encoded polypeptide. Along the coding region of messenger RNA, many ribosomes move to create a polysome.
So, the correct answer is 'Several ribosomes attached to a single mRNA'.
