If you increase exposure by one stop from f/11 @ 1/250 using only the shutter, your new setting would be?

Explanation:
Exposure increases when more light reaches the sensor, and one stop means the light is doubled. If you want to gain one stop by changing only the shutter, you double the shutter time while keeping the aperture the same. From 1/250, that becomes 1/125, with the aperture staying at f/11. So the correct setting is f/11 at 1/125. The other options don’t fit this constraint: f/8 at 1/125 would increase light by more than one stop (opening the aperture adds a stop while the shutter change adds one, totaling two). f/11 at 1/250 is unchanged. f/16 at 1/500 decreases exposure by two stops.
