Answer:

D is 7 and C is 1.

17x7 = 119  verified.

Step-by-step explanation:

In order to get 9 at the units digit, D can be either 3 or 7.

Now the remaining digits, that is 11 tells us that D cannot be 3, as because 11 is not fully divisible by 3.

Therefore, D is 7. And we have a carry of 4 to add with the product of D and C to match 11.  Therefore, C must be 1.

Let's verify:

17x7 = 119  verified.
