Solution

The answer is the second one (400 ml): Stretch receptors in the bladder will normally trigger a signal to the spinal cord when the bladder is holding around 400 ml of urine.

Explanation for each option:

200 ml: This volume is typically too low to trigger the stretch receptors in the bladder to send a signal to the spinal cord. At this volume, the bladder is not yet sufficiently distended to activate the receptors.
400 ml: This is the correct volume. At around 400 ml, the bladder is sufficiently filled to activate the stretch receptors, which then send a signal to the spinal cord indicating the need to urinate.
50 ml: This volume is far too low to trigger the stretch receptors. The bladder would not be significantly stretched at this volume.
600 ml: While the bladder can hold this much urine, the stretch receptors typically trigger a signal before reaching this volume to prevent overdistension and potential damage.

Summary: Stretch receptors in the bladder will normally trigger a signal to the spinal cord when the bladder is holding around 400 ml of urine.
