The quotient of two algebraic expressions is a<em> fractional expression.
</em> Moreover, the quotient of two <em>polynomials</em> such as:

is called a rational expression. So according to this definition rational expressions does not contain logarithmic functions. In fact, a rational expression is an expression that is the ratio of two polynomials like this:

Answer:
A. cos(
)
Step-by-step explanation:
Typed the all the expressions into desmos and picked the ones that matched
Let the angle be x and it's complement be c.
Then, x = c + 88 and x + c = 90
Substitute the first equation in the second.
(c+88) + c = 90
2c+88 = 90
2c = 2
c =1
Compliment = 1
Angle = 89
