This is how you would guess the answer.
Surface level is 14 psi. Assume 41000 feet (normal ceiling) is near to zero. The pressure drops to half around 10000 feet ie 7 psi.
Cabin altitude is typically 8000 feet so between 14 psi and 7 psi - let's guess 9 psi. This gives you (0 -9 ) as a maximum which rules out a couple of the options. I think it also rules out the low option as being too far from 9.
Ergo one answer left.
