D) blindsight.

The cocktail party effect refers to the ability to focus one's attention on a single auditory stimulus while filtering out other stimuli in the environment. In this case, Carolina was able to filter out her mother's voice while focusing on her text message, which is an example of the cocktail party effect. Dual processing refers to the idea that information is processed both consciously and unconsciously, and is not relevant to this scenario. Change blindness and blindsight both refer to specific visual phenomena, which are not applicable to this scenario.
