During the Gilded Age the US population rose
from under 20 million in 1830 to around 40 million in 1850.
from under 20 million in 1850 to about 40 million in 1870.
from nearly 40 million in 1870 to nearly 80 million in 1900.
from nearly 40 million in 1870 to over 100 million in 1910.

Answer 1

"From nearly 40 million in 1870 to nearly 80 million in 1900."

The graph shows about 38–40 million in 1870 and about 76 million in 1900, so option 3 is correct.
