Question Analysis
This problem evaluates the student's understanding of determining the horizontal asymptote of a rational function where the degrees of the numerator and the denominator are both 1.

Key Concept Explanation
When the degrees of the numerator and the denominator are equal, the horizontal asymptote is given by the ratio of the leading coefficients.

Step-by-step Solution
1. Identify the degrees of the numerator and the denominator. Both are 1.
2. The horizontal asymptote is given by the ratio of the leading coefficients:
