The correct relationship between Arithmetic Mean (A.M.), Geometric Mean (G.M.), and Harmonic Mean (H.M.) is:

Correct option is D

The relationship between means is A.M. ≥ G.M. ≥ H.M.
Arithmetic Mean is always the largest.
Geometric Mean lies between the Arithmetic and Harmonic Means.
Harmonic Mean is always the smallest.
