Which of the following psychological statements is most authentic and scientifically valid regarding the 'General Factor' (g-factor) and 'Specific Factor' (s-factor) proposed under Charles Spearman's 'Two-Factor Theory of Intelligence', and their scientific management in classroom teaching regarding students' cognitive abilities, academic proficiency, and specific-skill-based aptitudes?

Charles Spearman (1904) proposed the Two-Factor Theory of intelligence. According to him, two types of factors operate in every intellectual task: (1) General factor or 'g-factor', which is generally present in all mental activities and is a type of universal mental energy, and (2) Specific factor or 's-factor', which is required for a specific activity or field (such as music, art, mathematical proficiency, etc.). In classroom teaching and differentiated instruction, teachers should respect students' general intellectual capacity ('g-factor') while providing opportunities to hone their specific skills ('s-factor').
