Concept:A rational number can be written as a fraction $\frac{p}{q}$ (with $q \neq 0$). Its decimal expansion either ends (terminates) or eventually repeats a block of digits.Explanation:When you divide numerator by denominator, the remainder must be between 0 and $q-1$.If at any step the remainder becomes 0, the division ends — this gives a terminating decimal.If the remainder never becomes 0, the process repeats because only $q$ different remainders exist. Hence the decimal digits repeat in a cycle.So the decimal expansion of any rational number is either terminating or repeating (recurring).Answer:Option B (Terminating or repeating).
