Answer:
The correct answer is option - A. Gametophyte, C. spore, and D. sperm.
Explanation:
The egg cell of a plant is haploid in the cell which means it has only one set of chromosomes. The haploid cells arise from the meiosis cell division in parent sex cells. These parent cells are divided into four cells with half of the chromosome number in comparison to the parent cells.
The gametophyte, spore, and sperm all three are the product of the meiosis division and are haploid in number.
Thus, the correct answer is option - A, gametophyte, C. spore and D. sperm.

Homologous and analogous structures are two types of evolutionary evidence, taken together, provide strong evidence for when extinct species most likely diverged from common ancestors, relative to other events happening on Earth.
Several types of evidence support the theory of evolution: If two or more species share a unique physical feature, such as a complex bone structure or body plan, they can all inherit this property from the common ancestor. Physical traits shared through evolutionary history (common ancestor) they say they are homologous. Not all physical properties that look similar are signs of common ancestry. Some physical similarities instead are analogous: they evolved independently in different organisms because organisms lived in similar environments or experienced similar selective pressures.
