The word "inquisitive" is defined as having a strong desire to learn or know more; being curious. Therefore, while it does not directly correlate with the options you've provided, the closest interpretation would involve a willingness to explore and ask questions, which aligns more with being curious rather than strictly thinking critically or creatively.
If we consider your options:
a) To be able to think creatively - partially relevant since inquisitiveness can lead to creative thinking. b) To be able to think critically - also somewhat relevant as inquisitiveness can drive critical analysis. c) To be able to think critically and creatively - this option encompasses both aspects of being driven to learn and explore.
While none of the options perfectly define "inquisitive," option c) would encompass both the critical and creative sides of inquiry.
