You need to evaluate `u/x + (5u)/x - u/(5x)` , hence, you need to bring the terms to a common denominator, such that:

`u/x + (5u)/x - u/(5x) = (5u + 25u - u)/(5x)`

`u/x + (5u)/x - u/(5x) = (29u)/(5x)`

Hence, evaluating the expression `u/x + (5u)/x - u/(5x)` yields `u/x + (5u)/x - u/(5x) = (29u)/(5x)` , thus, you need to select C option.
