Bacteriophages are bacteria-infecting viruses.

The T4 phage, which infects Escherichia coli, has a polyhedral head connected to a helical tail, a typical bacteriophage structure.

Many phages have fibres in their tails that adhere to the host cell.

Thus, the correct answer is 'A - Head, B - Sheath, C - Collar, D - Tail fibres'.
