I believe choice D is the correct answer.

Irrational means it repeats infinitely, but not in repeating blocks, so I believe choice (B) is the answer.

Any terminating or repeating decmal can aways be written as a rational number

 

The square root of any non-square will always be irrational

 

So....tertre is correct
