Which word describes someone who is ingenious?

The term "ingenious" refers to a person who possesses a high degree of inventiveness, creativity, and skill in devising solutions or creating things. When we describe someone as ingenious, we are highlighting their ability to think outside the box and come up with innovative ideas or methods. This is why the choice that indicates "showing inventiveness and skill" accurately captures the essence of what it means to be ingenious.

In contrast, other descriptions do not align with the definition of ingenious. For instance, lacking in creativity and skill suggests an absence of the very qualities that define ingenuity. Being overly simplistic implies a lack of complexity or depth, which contradicts the nuanced thinking typically associated with ingenuity. Finally, describing someone as restrained and conservative suggests a tendency to adhere to traditional methods or ideas rather than embracing the creativity and inventiveness central to being ingenious.
