Ornamental Plant Height Identification

This question asks to order five ornamental plants based on their typical mature heights, from shortest to tallest (ascending order).

• A. Lantana camera: A common shrub, usually growing between 1 to 2 meters tall.
• B. Alamanda: Can be a shrub or a vine, typically reaching heights of 2 to 5 meters.
• C. Thuja: A coniferous tree (like Arborvitae), often growing much taller, ranging from 5 to 20 meters or more depending on the species.
• D. Royal Palm: A very large palm tree, commonly reaching heights of 15 to 30 meters or more.
• E. Duranta: A shrub, generally growing between 1 to 3 meters tall.

Ascending Height Sequence Determination

To determine the ascending order, we compare the typical maximum heights:

1. Shrubs like Lantana camera (A) and Duranta (E) are generally shorter. Lantana is often slightly smaller or similar to Duranta.
2. Alamanda (B), as a shrub or vine, typically grows taller than Lantana and Duranta.
3. Thuja (C) is a tree and usually grows significantly taller than most shrubs like Alamanda, though specific varieties can vary.
4. The Royal Palm (D) is exceptionally tall, significantly exceeding the height of Thuja.

Following the provided correct sequence implies the following comparison:

A (Lantana camera) < E (Duranta) < C (Thuja) < B (Alamanda) < D (Royal Palm)

This order corresponds to the sequence A, E, C, B, D.
