Spoiler
CW is correct. The logic behind it:
There can be at most one statement correct: if there were two or more they would always contradict each other.
Assume there was no correct statement then there would be 973 false statements. This is exactly what the statement on page 973 says. But this statement would be true then so this contradicts.
Assume there is one, then the other statements would be false so 973 - 1 = 972 statements would be false. This is exactly what the statement on page 972 says.
This is the correct answer.
