Which explanation best describes the use of "a little" in terms of eye contact?

The phrase "a little" refers to a small amount or degree of something. In the context of eye contact, it suggests that there is some degree of eye contact being made, but it is not overwhelming or extensive. This expression typically conveys that while there may be fleeting or minimal engagement through eye contact, it does exist. Thus, saying there is "a little" eye contact implies the presence of interaction, which can foster connection and understanding between individuals during a conversation.

The other options describe varying quantities of eye contact that either exaggerate or contradict the intent behind "a little." Expressions suggesting a higher level, a complete lack, or consistent engagement with eye contact do not align with the nuance of minimal connection embodied in the phrase "a little."
