Answer 2

Man's voice < Baby's voice < Woman's voice

Explanation:

The higher the pitch, shriller the voice. Sounds produced by the vocal cords of women are of higher frequency and so shriller than men and babies. Men have a deep voice as their vocal cord produces the least frequency among the given list. They are of lower pitch than the babies and women. In the order of increasing frequency, the voices are as follows:

Man's voice < Baby's voice < Woman's voice
