The correct option is A Capsule/sporangium
The life cycle of funaria is of two types i.e., sexual and asexual. The sexual lifecycle is haplodiplontic where the haploid gametophyte alternates with diploid sporophyte. The spore is the first cell of gametophyte which develops into mature gametophyte bearing antheridia and archegonia (sex organs). The antheridia bear the antherozoids which swim to the archegonia and fuses with the egg. After fertilisation, the zygote divides to form sporophyte. The sporophyte consists of foot, seta and capsule. Inside the capsule, the haploid spores are formed by meiosis. Thus, the correct answer A.
