Explanation
The correct answer is C, 50 metres. An Olympic-size or long course pool measures 50 metres in length and 25 metres in width, and all Olympic pool races are swum in it, so a 100 metre race means two lengths and the 1500 metre freestyle means thirty. Option A is wrong because 25 metres is the short course pool used for the World Short Course Championships and for most club meets; records set in it are listed separately from long course records. Option B is wrong because 33 metres matches no recognised standard, though pools of that rough size were used at some very early Olympic Games before the distance was fixed. Option D is wrong because no competition pool is 100 metres long; the 100 metre race is covered in two lengths of a long course pool. The width of 25 metres holds ten lanes of 2.5 metres each.
