The correct option is D 3,1
Euclid's division lemma:
Let a and b are two positive integers, then there exist unique integers q and r such that
a = bq + r, where 0 ≤ r < b.
Now put the value in such a way that it satisfies the given equation below.
∴ 25 = 8 × 3 + 1
⇒ Quotient, q = 3 and remainder, r = 1
