There are 5 tiles of

, 2 tiles of x and 5 tiles of 1.
The similar tiles can be added up and represented as a single term. So 5 tiles of

can be written as

. 2 tiles of x can be written as 2x and 5 tiles of 1 can be written as 5.
The overall polynomial will be the summation of all these tiles. So the resulting polynomial will be

.
Thus the answer to this question is option C.
