Mosses spend most of their life cycle in the gametophyte phase.
To determine the phase in which mosses spend most of their life cycle, we can first understand the life cycle of mosses. The life cycle of mosses alternates between two distinct phases: the gametophyte phase and the sporophyte phase.
The gametophyte phase is the dominant and longest phase in the moss life cycle. During this phase, the moss develops from a spore into a mature plant. The mature gametophyte produces gametes, which are reproductive cells.
On the other hand, the sporophyte phase is a relatively short-lived phase in the moss life cycle. It is the phase in which the moss produces haploid spores through a process called sporogenesis. Sporophytes grow on the gametophyte and rely on them for nutrition.
Based on this information, we can conclude that mosses spend most of their life cycle in the gametophyte phase. Therefore, the correct response to the question "In what phase do mosses spend most of their life cycle?" is "gametophyte."
