The mode on the dial that requires you to manually set shutter speed and aperture is...

• A. Auto
• B. Shutter Priority
• C. Manual
• D. Program

Answer: (C)

Manual exposure mode gives you full control over exposure by letting you set both shutter speed and aperture yourself. The shutter speed determines how long the sensor is exposed to light, affecting motion in the shot, while the aperture controls how much light enters and the depth of field. In this mode you typically set ISO as well, using the camera’s meter or histogram to judge exposure. This is especially useful when lighting is tricky or you need a specific look, such as freezing action with a fast shutter or achieving a shallow or deep depth of field with a chosen aperture. Other modes automate one or both settings: Auto picks everything; Shutter Priority lets you choose the shutter speed while the camera picks the aperture; Program mode also selects both, sometimes with limited flexibility. So the mode that requires you to manually set both shutter speed and aperture is manual.
