In many cases in physics, one has to deal simultaneously with collective and single particle excitations of the system. The collective excitations are usually bosonic in nature while the single particle excitations are often fermionic. One is therefore led to consider a system which includes bosoms and fermions. Hence

Which of the following best completes the above argument?

A. in this book, we discuss application of bosonic particles and their consequences on physics.
B. in this book, we discuss applications of general algebraic theory of mixed Bose-Fermi systems to atomic nuclei.
C. in this book, we discuss excitations of collective and single particles separately.
D. in this book, we prove how collective excitations are bosomic and singular exciations are fermionic.
E. in this book, we prove the collective and singular excitation cannot exist together.

A is incorrect because their consequences are out of scope.
C is incorrect because the last sentence of the stimulus says we should consider them together, not separate.
D is incorrect because it is completely out of scope.
E is incorrect because we still want an answer that considers both together, not that they cannot exist togethor.

Therefore B is the correct answer because the bose-fermi systems means we are considering them togethor.
