C. oogamy only
D. anisogamy and oogamy

Answer

B

Explanation

(b) In Chlorophyceae, three types of sexual reproduction occurs, i.e. isogamy, anisogamy and oogamy. Isogamy involves the fusion of those gametes which are similar in size, shape and structure, e.g. Chlamydomonas debaryana. In anisogamy gametes differ morphologically and also behave differently, e.g. Chlamydomonas braunii. In oogamy, fusion between motile and non-motile gametes takes place, e.g. Chlamydomonas coccifera.
