Read the following statement and find out the incorrect statement.
(a). Asexual reproduction is common among single-celled organisms, and in plants and animals with relatively complex organisations.
(b) In yeast, the division is unequal and small buds are produced that remain attached initially to the parent cell which eventually gets separated and mature into yeast organism (cells).
(c). vegetative reproduction is also a type of asexual reproduction.
(d) While in animals and other simple organisms the term vegetative reproduction is used unambiguously, in plants the term asexual reproduction is frequently used.
(e) Water hyacinth is also called 'Terror of Bengal'

Options

A. a and d
B. b and c
C. a and e
D. b and d

Answer

To find the incorrect statement among the given options, let's analyze each statement step by step:

### Step 1: Analyze Statement (a)
**Statement:** Asexual reproduction is common among single-celled organisms, and in plants and animals with relatively complex organizations.

**Analysis:** Asexual reproduction is indeed common among single-celled organisms. However, in plants and animals with relatively complex organizations, sexual reproduction is more prevalent. Therefore, this statement is incorrect.

### Step 2: Analyze Statement (b)
**Statement:** In yeast, the division is unequal and small buds are produced that remain attached initially to the parent cell which eventually gets separated and mature into yeast organism (cells).

**Analysis:** This statement accurately describes the process of budding in yeast, which is a form of asexual reproduction. Hence, this statement is correct.

### Step 3: Analyze Statement (c)
**Statement:** Vegetative reproduction is also a type of asexual reproduction.

**Analysis:** This statement is true. Vegetative reproduction involves the production of new plants from the vegetative parts of the parent plant, which is indeed a form of asexual reproduction.

### Step 4: Analyze Statement (d)
**Statement:** While in animals and other simple organisms the term vegetative reproduction is used unambiguously, in plants the term asexual reproduction is frequently used.

**Analysis:** This statement is misleading. In animals and simpler organisms, asexual reproduction is more common, while in plants, vegetative reproduction is a specific type of asexual reproduction. Therefore, this statement is incorrect.

### Step 5: Analyze Statement (e)
**Statement:** Water hyacinth is also called 'Terror of Bengal'.

**Analysis:** This statement is true. Water hyacinth (Eichhornia crassipes) is known as the "Terror of Bengal" due to its invasive nature and its ability to outcompete native species.

### Conclusion
The incorrect statements are:
- (a) Asexual reproduction is common among single-celled organisms, and in plants and animals with relatively complex organizations.
- (d) While in animals and other simple organisms the term vegetative reproduction is used unambiguously, in plants the term asexual reproduction is frequently used.

### Final Answer
The incorrect statements are (a) and (d).
