anonymous · Answer

Well i believe that we can cancel out B and D because fractions can not be irrational

All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point.
