1. The problem asks to write a rational expression in lowest terms, but the specific expression is not provided. 2. To simplify a rational expression, factor both the numerator and denominator completely. 3. Then, cancel out any common factors that appear in both numerator and denominator. 4. The result is the rational expression in its lowest terms. 5. Without the actual expression, we cannot perform these steps explicitly. 6. Please provide the rational expression or the options (A, B, C, D) to proceed with simplification.
