.............. does not experience any change in tidal level.

  • A.Average tide level
  • B.Co-range line
  • C.Amphidromic point
  • D.Co-tide line

Answer: C

The answer is the Amphidromic point.

In each ocean basin the tide wave rotates around points where the tidal range is zero, called amphidromic points. Co-tidal lines (joining places with high tide at the same time) radiate out from them like spokes, and co-range lines (joining places with equal tidal range) form circles around them, with the range increasing away from the point.

A co-range line has a constant tidal range, not zero range, and a co-tidal line marks equal timing of high water. Average tide level is a reference datum, not a place that experiences no tidal change.
