Fluid intelligence is characterized by the capacity to think logically and solve problems in novel situations, independent of acquired knowledge. It involves the ability to analyze and process information quickly and efficiently, which reflects "on the spot reasoning." This type of intelligence is crucial for tasks that require abstract thinking and adaptability, as it allows individuals to approach unfamiliar challenges without relying on previously learned facts or experiences.

Fluid intelligence is often contrasted with crystallized intelligence, which refers to the knowledge and skills that are acquired through experience and education. While crystallized intelligence builds on past learning, fluid intelligence is more about the immediate application of reasoning skills to new problems. In the context of the question, "on the spot reasoning" directly aligns with the attributes of fluid intelligence, making it the correct choice for this scenario.
