Final answer:
Body-Kinesthetic intelligence is the best fit for the definition 'May fidget during class'.
Step-by-step explanation:
Gardner's Multiple Intelligences Theory categorizes different types of intelligence. The word that best fits the definition 'May fidget during class' is Body-Kinesthetic intelligence. This type of intelligence relates to physical movement and coordination, and individuals with high body-kinesthetic intelligence tend to be more physically active and may have difficulty sitting still for long periods of time.
