Question Analysis
This problem tests the understanding of determining the horizontal asymptote of a rational function where the degree of the numerator is less than the degree of the denominator.

Key Concept Explanation
When the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is the x-axis, which is .

Step-by-step Solution
1. Identify the degrees of the numerator and the denominator. The degree of the numerator is 1, and the degree of the denominator is 2.
2. Since the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is always
