Read the passage given below and answer the following questions from (i) to (v).
Asexual reproduction, in which offspring arise from a single organism, occurs in a variety of prokaryotes and eukaryotes including plants, fungi, and animals. It may have some advantages over the sexual reproduction, in which individuals of two genders, females and males, must be involved but only females can give birth to new individuals. There are several different methods of asexual reproduction. Asexual reproduction can be very rapid. This is an advantage for many organisms. It allows them to crowd out other organisms that reproduce more slowly.
(i) Budding is a mode of asexual reproduction in:
Amoeba
Plasmodium
yeast
Leishmania
