Which term describes someone who is anxious or concerned?

The term "sollicitous" accurately describes someone who is anxious or concerned. This word embodies a sense of eagerness to care for others or a deep concern about their well-being. When someone is solicitous, they are often attentive and show a genuine interest in ensuring that things are well or that someone's needs are met, reflecting their anxiety or concern for that person's situation.

In contrast, the other options convey different attitudes or characteristics. "Pliable" suggests flexibility or the ability to be easily influenced, which does not inherently relate to feelings of concern. "Indifferent" describes a lack of interest or concern about something, which is directly opposite to being anxious or solicitous. Lastly, "complacent" refers to a self-satisfied state, where someone might feel so content that they overlook potential dangers or problems, again contrasting with the notion of anxiety or concern.

Thus, "sollicitous" is the term that accurately reflects a state of concern or anxiety regarding someone or something.
