Using translation concepts, it is found that the correct option is:

D. It is the graph of translated 3 units up and 7 units to the right.

The parent function is:


f(x)=y=1nx

Shifting a function a units to the right is equivalent to finding f(x - a), thus:


f(x-7)=1n(x-7)

Shifting a function a units up is equivalent to finding f(x) + a, thus:


f(x-7)+3=1n(x-7)+3

Which means that the function was shifted 7 units to the right and 3 up, thus, option D is correct.
