Answer: OPTION B
Step-by-step explanation:
You need to remember that, to subtract radicals, the indices and the radicands must be the same.
Given the expression 
, you can identify that both have index 2 and the radicands are 2 (The numbers that are inside of radicals), therefore, you can conclude that the subtraction can be made.
Then, you must subtract the terms in front of the radicals. Therefore, you get:
You can observe that this matches with the option B.

142 / 12 = 11 and 10/12 or 11 and 5/6
142 inches is the equivalent of 11 and 5/6 feet or 11.83333... feet. (... because it repeats 3s forever.
EDIT: said "142 feet" instead of *inches in the last statement
93-10=83-10=73-10=63-10=53-10=43-10=33-10=23-10=13-10=3
so 93÷10=9 remainder of 3
