The correct options are
B There is no fusion of gametes.
C Young ones formed are exact copies of their parents.
D It involves only mitotic cell division.
In asexual reproduction, only a single parent is involved and hence it is called uniparental. Since there is no fusion of gametes, the young ones formed will be exact copies of their parents and are referred as clones. It involves only mitotic division i.e., a type of cell division where a single parent divides into two daughter cells.
