C Correct answer
Explanation

The correct matching is: Geosynclinal Theory (A) relates to mountain building processes (3) - geosynclines are large sedimentary troughs that become folded into mountains. Tetrahedral Hypothesis (B) explains the origin of continents and ocean basins (4) through a tetrahedral earth model. Stationary Wave Theory (C) relates to the origin of tides (1) through standing wave patterns. Subsidence Theory (D) by Darwin explains coral reefs and atolls (2) through gradual subsidence of volcanic foundations. The correct answer is A-3, B-4, C-1, D-2.
