Infloresence of liliaceae is

Options

A. actinomorphic
B. trimerous
C. pentamerous
D. (d) imperfect

Explanation

### Step-by-Step Solution:

1. **Identify the Family**: The question asks about the inflorescence of the Liliaceae family. This family includes plants such as onions (Allium cepa).

2. **Understand Inflorescence**: Inflorescence refers to the arrangement of flowers on a plant. In the case of Liliaceae, we need to determine the specific characteristics of their flowers.

3. **Analyze Flower Structure**: The flowers in the Liliaceae family are typically actinomorphic, meaning they can be divided into two equal halves by multiple planes. This symmetry is a key characteristic of their inflorescence.

4. **Examine Floral Formula**: The floral parts of Liliaceae are usually in multiples of three (trimerous), which includes the calyx, corolla, and androecium. This means that the flowers have three or six petals and sepals.

5. **Determine Flower Type**: The flowers in Liliaceae are perfect flowers, meaning they contain both male (androecium) and female (gynoecium) reproductive structures. This rules out the possibility of them being imperfect flowers.

6. **Conclude the Type of Inflorescence**: Based on the analysis, we conclude that the inflorescence of Liliaceae is trimerous and actinomorphic. Therefore, the correct answer to the question is that the inflorescence of Liliaceae is trimerous.

### Final Answer:
The inflorescence of Liliaceae is **trimerous**.
