In a scenario where two liquids are mixed and bubbles are observed without reaching the boiling point, the most likely explanation for the presence of bubbles is:
**D) air that was released from the liquids.**
When mixing certain liquids, especially those that are not fully miscible or contain dissolved gases, the agitation can result in the release of air (or other gases) that was previously trapped in the liquids. This phenomenon can lead to the formation of bubbles. Other options, such as the generation of gas from a reaction or volatiles from one of the liquids changing to gas, would typically correlate with a boiling or significant temperature change. Since it is specified that the mixture did not reach its boiling point, the release of dissolved air is the most plausible explanation for the observed bubbling.
