a

and

b

are two positive numbers, then

View answer and explanation

Correct option: D

A M \geq G M \geq H M

Option D (

A M \geq G M \geq H M

) is correct because for any two positive numbers, the Arithmetic Mean is always greater than or equal to the Geometric Mean, which is greater than or equal to the Harmonic Mean.
