In low light, which feature engages automatically in Full Auto mode?

• A. The flash is disabled
• B. The flash will automatically pop up
• C. The ISO will drop
• D. The white balance will adjust automatically

Answer: (B)

In low light, Full Auto mode uses whatever light is available to get a proper exposure, and the built-in flash is often the tool it chooses. The camera analyzes the scene; if it detects insufficient light, it automatically triggers the flash and makes it pop up to illuminate the subject. That automatic pop-up is the feature described, and it’s what helps prevent underexposure and motion blur when there isn’t enough ambient light.

Why the other ideas aren’t the best fit here: disabling the flash wouldn’t help in a dim scene, since Auto mode relies on adding light. Dropping the ISO isn’t necessary in low light—AUTO typically increases ISO to maintain exposure, not decrease it. White balance can adjust automatically, but that’s about color balance, not about a mechanical action like the flash engaging.
