What term refers to the crest of the wave causing tides; not a tsunami or seismic sea wave?

Explanation:
Think about how tides and waves are described. Tides are the regular rise and fall of sea level caused mainly by the gravitational pull of the Moon and Sun. A term that explicitly ties a wave to that tidal influence is “tidal wave”—a wave associated with the tidal system. The other options don’t fit this idea: a tide refers to the overall rise and fall, a calcareous ooze is a sediment type, and a clamshell sampler is a piece of equipment used to collect samples. So the word that best links to tides among these choices is tidal wave, since it directly invokes the tidal relationship with waves rather than a tsunami or a sampling device.
