Which type of lake does not hold water throughout the year?

Correct answer: Seasonal lake

The direct answer is B: a seasonal lake. A seasonal lake contains water mainly during a particular season, usually after rainfall, and may shrink greatly or become dry during the dry season. Its water level depends strongly on seasonal rain, inflow, evaporation, and sometimes groundwater. Option A, permanent lake, is wrong because a permanent lake normally retains water throughout the year, although its level may rise or fall. Option B is correct because “seasonal” means occurring or lasting only during certain seasons. Option C, deep lake, is wrong because depth describes how deep a lake is; it does not by itself mean that the lake lacks water for part of the year. A deep lake can be permanent. Option D, coastal lake, is wrong because coastal describes location near the sea, not whether water remains all year. A coastal lake may be permanent or seasonal. The key distinction is duration of water storage, not depth or location. Memory cue: seasonal water comes with the season and may disappear after the rains end.
