C Correct answer
Explanation

Many desert plants, like cacti, have shallow, widespread root systems that allow them to rapidly absorb water from light, brief rain showers before the moisture evaporates. Note that some desert plants also use extremely deep taproots to reach groundwater, making both root strategies valid adaptations.
