option number [a] is also right

Question:
A number 476**0 is divisible by both 3 and 11. The digit in the hundred and tenth place respectively are (if digits are non-zero). 
Options:
A) 7, 4
B) 7, 5 
C) 8, 5
D) 4, 3
Solution:
Ans: (c)

(4 + 7 + 6 + x + y + 0) =17 + (x + y)

or,(x + 7) – (y + 6 + 4) = x – y – 3

Now, [17 + (x + y)] must be divisible by 3

and (x – y – 3) is either 0 or divisible by 11.

Clearly x = 8, y = 5 satisfy both the conditions.
