The answer is; A
In pteridophytes, the sporophytes (of the haploid stage) produce spores. The diploid stage in pteridophytes may occur when tow spores fuse and develop into a prothallus (diploid stage of the pteridophytes).
Fungo too produces spores by the sporangiophores (haploid stage). Occasionally, two horizontal hyphae between two species of fungi, may fuse at the tips and form a zygote through karyogamy and plasmogamy.
Answer:
im not sure what your questions is about it could be
1) mutation, gene flow, genetic drift, and natural selection
or
2)reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.

Since there are a dominant and a recessive character, therefore, this is a case of Mendelian characters. There are some possibilities
1- Dominant pure SS is crossed with dominant pure SS, all the generation will be dominant.
2- Dominant Pure SS is crossed with recessive ss, aal the first generation will be dominant phenotype and impure genotype (Ss). The second generation will be 3 dominant: 1 recessive. The 3 dominant in the second generation will be 1 pure SS and two impure Ss.
3- Dominant Impure with recessive, the first generation will be 1 dominant impure : 1 recessive.
4- Recessive with recessive, the generation will be all recessive.
