Using only uniformitarian calculations from the thickness of known sedimentary rocks, likely rates at which those rocks accumulated, and features in and under those sedimentary rocks, geologists working two to three hundred years ago estimated that the Earth:

Incomplete question. The Options read;

a) Is about one-hundred-million years old.

b) Is 4.6 billion years old.

c) Has been here forever.

d) Is less than about one-hundred-million years old.

e) Is more than about one-hundred-million years old.

e) Is more than about one-hundred-million years old.

Explanation:

Remember, we are talking about the information available some two to three hundred years ago when there was no modern geological equipment for radioactive elements tracing.

Hence, using uniformitarian calculations from the thickness of known sedimentary rocks, the geologists concluded that the Earth must be more than about one-hundred-million years old. However, modern researchers today have concluded the Earth to be not millions but billions of years old.
