If 49 is dividend, 7 is the divisor and quotient is 7 then divisor into quotient will be equal to which of the following?

The correct option is (B).

Given- 49- dividend

7- divisor

7- quotient

Then, 

Divisor $\times$Quotient = $7\times 7=49$

Therefore, if 49 is dividend, 7 is the divisor and quotient is 7 then divisor into quotient will be equal to 49.
