C4 photosynthesis has a primary advantage in that it significantly reduces water loss during the process of photosynthesis. This type of photosynthesis is particularly advantageous in environments that are hot and dry. In C4 plants, the CO2 is initially fixed into a four-carbon compound, which allows them to keep their stomata closed more often to minimize water loss through transpiration. This adaptation enables C4 plants to maintain efficient photosynthesis even when water availability is low, making them well-suited for arid conditions.

While higher production of glucose and increased absorption of sunlight can be aspects related to photosynthesis, they are not the primary advantages of C4 pathways specifically. Additionally, the choice related to nitrogen fixation does not pertain to the advantages of C4 photosynthesis in the same context, as C4 plants are more known for their adaptations related to carbon fixation and water efficiency rather than any detrimental effects on nitrogen fixation processes. Therefore, the correct answer highlights this key benefit that C4 photosynthesis offers in terms of water conservation.
