The maximum degree of curvature for Meter Gauge is limited to A. 10° B. 16° C. 30° D. 40°

The correct answer is A. 10°.

The maximum degree of curvature for meter gauge is limited to 10°. This is because a sharper curve would make it difficult for trains to

negotiate the turn, and could potentially derail them.

The other options are incorrect because they are either too high or too low. A curve with a degree of curvature of 16° would be too sharp for most trains, and a curve with a degree of curvature of 40° would be too wide.

It is important to note that the maximum degree of curvature for meter gauge can vary depending on the specific railway line. However, 10° is a general guideline that is used by most railways.
