1) Not Sufficient : current sum is 19 . So the number can assume 1,5, or 9 to satisfy the statement :The sum of the 7 digits is equal to 4 times an integer.
2) Not Sufficient : Missing digits are :0,4,7,8, and 9
1+2) Sufficient : There is a common element in the 2 aforementioned sets. i.e., 9
Hence Ans C.
