Question

what is the key to insight? only occurs for creative people. just happens. is instinctual. takes practice.

Explanation:

Insight is not limited to creative people (so "Only occurs for creative people" is wrong), it doesn't just happen randomly (so "Just happens" is wrong), and it's not purely instinctual. Insight is a skill that can be developed through practice, so "Takes practice" is the correct option.

Answer:

D. Takes practice
