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 bosons and fermions. Hence, __________________
Which of the following options is most likely to follow the paragraph given above ?

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