Answer: Fluid intelligence
Step-by-step explanation:
Fluid intelligence is the intelligence that is based on the ability of mind for solving issues and thinking logically in seamless manner. A person does not face any obstruction in finding solution in this intelligence. Identifying patterns, understanding novel problems, relationships etc are the task performed through fluid intelligence.
