Answer:
C. 7 r99
Explanation:

We have,
First find the quotient.
When we multiply 126 by 7, we get 882
When we multiply 126 by 8, we get 1008
We cannot take quotient 8 because it gives 1008 which is more than Numerator.
So, we take Quotient as 7.
let's find the remainder.
Remainder is calculated by subtracting real numerator by Product of denominator and quotient.
Calculation:
Remainder:

So, the answer is C. 7 r99
Mathematically:
