A theory is said to have heuristic value if __________

A) it stimulates debate and motivates researchers to pursue research related to the theory.
B) it explains a fairly narrow area of behavior.
C) it focuses attention on observations that cannot be readily explained in other ways.
D) it provides solutions for real-world problems.

Heuristic value refers to the ability of a theory to inspire and guide further research, which is reflected in choice A as it mentions how the theory can stimulate debate and motivate researchers to pursue research related to the theory. Choices B and D do not accurately describe heuristic value, while Choice C is partially correct but does not capture the full essence of heuristic value.
