Answer: B
The epidermal ridges develop during the 3rd and 4th intrauterine month.
Volar pads appear on the fingers and palms of the fetus around the seventh to tenth week. As they regress, the friction ridges form, beginning around the tenth week and fully developed by about the 16th to 17th week, that is, during the third and fourth months. After that the pattern stays the same for life, growing only in size.
By the 7th to 9th months the ridges are long complete, and in the first month there are no ridges at all.
