Study the following figures and select the correct statements regarding these.
(i) A shows mode of asexual reproduction in sponges through internal buds.
(ii) B shows sexual reproduction through zoospores in Chlamydomonas.
(iii) C shows asexual reproduction through conidiospores in Penicillium.
(iv) D shows external budding in Sycon.

The correct option is C (i), (iii) and (iv)
$B$ shows asexual reproduction through zoospores in Chlamydomonas. The zoospores are special kind of motile and flagellated spores produced inside the zoosporangia. They are generally naked (without cell wall). The flagella helps to swim in aquatic habitat for proper dispersal.

So the correct answer is '(i), (iii) and (iv)'
