►Since Dividend = Divisor � Quotient + Remainder, we have three divisors D1, D2, D3, as 3, 4, 7 and their respective remainders as R1, R2, Ras 2, 1, 4.

►Taking quotient Q= 1, we have D� Q3 + R3 = 7 � 1 + 4 = 11. Now 11 becomes Q2 for D2 and so on.

►Now solving 4 � 11 + 1 = 45, 3 � 45 + 2 = 137.

►Now when 84 divides 137 remainder is 53.

Hence Option D is correct
