"creating distinct temperature layers that can influence the distribution of marine life" — correct.

Brief explanation: thermal stratification produces a warm, well-lit surface layer, a sharp thermocline (rapid temperature change), and a colder deep layer. That structure controls vertical mixing of heat, oxygen and nutrients, so it concentrates plankton and fish near favorable layers, can limit nutrient supply to the surface (reducing productivity) or trap oxygen-poor water at depth (creating hypoxic zones), and influences seasonal cycles (spring/fall turnover) and habitats for different species. The other options are incorrect: stratification does not make the ocean uniformly warm, doesn't prevent deep life entirely, and doesn't cause bottom-up freezing.
