1 day = 24 hours，$$1$$ hour = 60 minutes，$$1$$ minute = 60 seconds，$$24$$ days = (24 \times 24) hours = [(24\times 24) \times 60] minutes = 24\times 24\times 60\times 60 seconds 
Which of the following calculations shows how to work out the number of seconds in~~24 days? 

(A) 24 \times 24~ 
(B) 24 \times 60 
(C) 24 \times 24 \times 60 
(D) 24 \times 60 \times 60 
(E) 24 \times 24 \times 60 \times 60
