Correct Option: B. Ficus elastica (Rubber Plant) Detailed Explanation: Why Ficus elastica is the Correct Answer:

1. Striking Foliage: Ficus elastica, commonly known as the Rubber Plant, is renowned for its large, glossy leaves that can be deep green or variegated with shades of cream or yellow. This striking foliage makes it a popular choice for ornamental use in landscaping and interior decoration.
2. Low Maintenance Requirements: One of the key reasons Ficus elastica is favored in landscaping is its low maintenance needs. It is relatively drought-tolerant once established, requires minimal pruning, and can thrive in a variety of light conditions, from low light to bright indirect sunlight. This makes it an ideal choice for both novice and experienced gardeners who may not have the time or resources for high-maintenance plants.
3. Versatility: The Rubber Plant can be used in various settings, including indoors, patios, and gardens. Its ability to adapt to different environments adds to its appeal as a landscaping option.
4. Air Purification: Additionally, Ficus elastica is known for its air-purifying qualities, which can improve indoor air quality, making it a beneficial choice for both aesthetic and health reasons.

Why the Other Options are Incorrect or Weaker: A. Rose (Rosa spp.): - Maintenance: While roses are beautiful and popular ornamental plants, they require significant care, including regular pruning, pest management, and specific soil conditions. They are not considered low maintenance, which makes them less suitable for the question's criteria. - Foliage: Roses are primarily valued for their flowers rather than their foliage, which does not align with the question's focus on striking foliage. C. Petunia (Petunia spp.): - Seasonal Nature: Petunias are annual flowering plants that require regular deadheading and watering to maintain their appearance throughout the growing season. They are not as low maintenance as Ficus elastica. - Foliage: While petunias have attractive flowers, their foliage is not particularly striking compared to the large, glossy leaves of the Rubber Plant. D. Marigold (Tagetes spp.): - Maintenance: Marigolds are also annuals that require regular care, including deadheading and watering. They are not as resilient as Ficus elastica in terms of maintenance. - Foliage: Similar to petunias, marigolds are primarily appreciated for their bright flowers rather than their foliage, which does not meet the question's criteria for striking foliage. Summary of Key Points:

• Ficus elastica (Rubber Plant) is known for its striking, glossy foliage and low maintenance requirements, making it ideal for landscaping.
• Other options like roses, petunias, and marigolds require more care and are primarily valued for their flowers rather than foliage.
• The Rubber Plant's adaptability and air-purifying qualities further enhance its appeal as an ornamental plant.
• Understanding the maintenance needs and aesthetic qualities of plants is crucial for effective landscaping choices.
