Step 1: Understanding Spearman's theory of intelligence
- Charles Spearman proposed the "g-factor" theory of intelligence, suggesting that intelligence is composed of a general ability (g) and specific abilities (s). He believed that individuals who perform well in one cognitive task tend to perform well in other tasks as well.
Step 2: Analyzing the options
- (A) 2: Correct. Spearman believed that intelligence could be measured by two factors: general intelligence (g) and specific abilities (s).
- (B) 4: Spearman did not propose that intelligence consists of four factors.
- (C) 5: Spearman's theory did not involve five factors of intelligence.
- (D) 7: There is no reference in Spearman's theory to seven factors of intelligence.
Step 3: Conclusion
Thus, the correct answer is (A) 2, as Spearman proposed that intelligence is composed of a general factor (g) and specific factors (s).
\[
\boxed{\text{Correct Answer: (A) 2}}
