Options

A. bisexual
B. polygamous
C. bigamous
D. monoecious

Answer

To determine the correct term for a plant that bears unisexual, bisexual, and neutral flowers, we can analyze the options provided:

1. **Bisexual**: This refers to flowers that contain both male (stamens) and female (pistils) reproductive structures within the same flower. However, this does not account for unisexual or neutral flowers.

2. **Polygamous**: This term describes a plant that has a combination of unisexual flowers (either male or female), bisexual flowers, and neutral flowers (which lack reproductive structures). This option fits the criteria given in the question.

3. **Bigamous**: This term typically refers to a situation involving two marriages or unions. In the context of flowers, it implies the presence of both unisexual and bisexual flowers, but it does not include neutral flowers.

4. **Monoecious**: This term refers to plants that have both male and female flowers on the same plant, but it does not include neutral flowers.

Based on this analysis, the correct answer is **Polygamous** (Option 2), as it encompasses the presence of unisexual, bisexual, and neutral flowers.

### Step-by-Step Solution:
1. **Understand the definitions**: Familiarize yourself with the terms related to flower types: bisexual, unisexual, neutral, polygamous, bigamous, and monoecious.
2. **Analyze each option**: Evaluate each option based on the definitions and determine if they meet the criteria of having unisexual, bisexual, and neutral flowers.
3. **Identify the correct term**: Conclude that the term that includes all three types of flowers is "polygamous."
4. **Select the answer**: Choose the second option, "polygamous," as the correct answer.
