Under Charles Spearman's 'Two-Factor Theory of Intelligence', which of the following psychological statements regarding the real psychological implications of the 'General Factor' (g-factor) and 'Specific Factor' (s-factor), and their relationship to the assessment of students' intellectual capacities and academic performance in classroom teaching, is most authentic and scientifically valid?

Charles Spearman (1904) proposed the Two-Factor Theory of Intelligence. According to him, two types of factors operate in intellectual activities:

• General Factor (g-factor): It is universally present in all types of intellectual operations and represents innate mental energy, governing general cognitive tasks and abstract reasoning.
• Specific Factor (s-factor): It is related to specific domains (such as music, mathematics, painting, etc.) and can be developed through training and practice.

In classroom instruction, the 'g-factor' facilitates general reasoning, comprehension, and academic adaptation, while the 's-factor' helps refine specialized skills based on individual differences. Therefore, option (b) is the most authentic and scientifically valid statement.
