Answer:
mean proportion means a same number should come in between these two numbers.
Step-by-step explanation:
16 : __ : 25
Use product of means = product of extremes
Hence 16 x 25 should be a perfect sqaure.
16 x 25 = 400
sqrt of 400 is 20
Hence 20 is the mean proportion between 16 and 25.
Hence A is the answer.
