Answer: (B)

Verified step by step guidance

1. Understand the zones of a lake: Lakes are divided into distinct zones based on depth and distance from the shore. These include the littoral zone, limnetic zone, profundal zone, and benthic zone.
2. Define the littoral zone: The littoral zone is the shallow area near the shore where sunlight penetrates all the way to the bottom, allowing rooted plants to grow.
3. Define the limnetic zone: The limnetic zone is the open water area away from the shore where sunlight penetrates but does not reach the bottom, so rooted plants cannot grow here.
4. Define the profundal zone: The profundal zone is the deep, dark area of the lake where sunlight does not reach, making it unsuitable for rooted plants.
5. Define the benthic zone: The benthic zone refers to the bottom of the lake, which can include areas in both the littoral and profundal zones. Rooted plants are typically found in the benthic areas of the littoral zone where sunlight is available.
