• A. F/4
• B. F/8
• C. F/11
• D. F/16

Answer: (D)

Stopping down the aperture increases depth of field, making more of the scene appear sharp from near to far. When you want foreground to background in focus, you choose a small aperture. Among the options, the smallest opening listed is f/16, which provides the greatest depth of field and helps keep both near and far subjects acceptably sharp. Just be aware that at very small apertures diffraction can soften the image, but within these choices f/16 offers the maximum depth. If you want even more precision, focusing at the hyperfocal distance can push the closest sharp point farther away, maximizing sharpness from foreground to infinity.
