To add 5 ft 8 in + 1 ft 9 in, we first need to convert the inches into feet. 8 in is equivalent to 0.67 ft and 9 in is equivalent to 0.75 ft (1 ft = 12 in). 
Therefore, we have:
5 ft 8 in + 1 ft 9 in = 5 ft + 0.67 ft + 1 ft + 0.75 ft 
= 7 ft + 0.42 ft
Now, we can convert the 0.42 ft back into inches. 0.42 ft is equivalent to 5.04 in (1 ft = 12 in). 
So, the final answer is: 
7 ft 5.04 in 
This can also be written as 2 yd 1 ft 5.04 in. However, option C is the best choice as it expresses the answer in both yards and feet.
