An effective public servant must always be ______ of the needs and desires of the community.

The correct choice is "conscious," which means being aware of and able to think about something. In the context of being an effective public servant, being conscious of the needs and desires of the community is essential. This awareness enables public officials to make informed decisions, provide services that genuinely meet the public's needs, and engage with community members effectively.

Being conscious involves attentiveness to the dynamics of the community, understanding its values, priorities, and challenges. This awareness allows for responsive and responsible governance, which is fundamental for fostering trust and cooperation between public servants and the community they serve.

The other terms do not correctly convey the intended meaning. For example, "conchess" is not a recognized word in the English language, while "consious" is a misspelling of "conscious." "Conscience," on the other hand, relates to moral understanding but does not relate specifically to being aware of community needs in terms of public service. Thus, the correct answer effectively encapsulates the necessity for public servants to be aware and attentive to those they serve.
