Select the incorrect statement out of the following.

Options

A. All animals belonging to various phyla are assigned to the kingdom Animalia.
B. As we go higher from species to kingdom, number of common characteristics goes on increasing.
C. Different classes comprising fish, amphibians, reptiles, brids and mammals together constitute the phylum Chordata.
D. Plant order Polymoniales includes the families like solanaceae and Convolvulaceae based on the vegetative and floral characters.

Explanation

To solve the question of selecting the incorrect statement out of the provided options, we will analyze each statement step by step.

### Step 1: Analyze the First Statement
**Statement:** All animals belonging to various phyla are assigned to kingdom Animalia.

**Analysis:** This statement is correct. The kingdom Animalia includes all animals, which are categorized into various phyla such as Porifera, Cnidaria, Annelida, Echinodermata, Arthropoda, and others.

### Step 2: Analyze the Second Statement
**Statement:** As we go higher from species to kingdom, the number of common characteristics goes on increasing.

**Analysis:** This statement is incorrect. In taxonomic hierarchy, as we move from species to kingdom, the number of common characteristics decreases. Species are the most similar organisms, while kingdoms encompass a broader range of organisms with fewer shared characteristics.

### Step 3: Analyze the Third Statement
**Statement:** Different classes comprising fish, amphibians, reptiles, birds, and mammals together constitute the phylum Chordata.

**Analysis:** This statement is correct. Fish, amphibians, reptiles, birds, and mammals are all part of the phylum Chordata, which is characterized by the presence of a notochord at some stage of development.

### Step 4: Analyze the Fourth Statement
**Statement:** Plant order Polymoniales includes the families like Solanaceae and Convolvaceae based on the vegetative and floral characters.

**Analysis:** This statement is correct. The order Polymoniales does include families such as Solanaceae (nightshades) and Convolvaceae (morning glories), which are classified based on their vegetative and floral characteristics.

### Conclusion
After analyzing all the statements, the incorrect statement is the second one: "As we go higher from species to kingdom, the number of common characteristics goes on increasing."

### Final Answer
**The incorrect statement is:** "As we go higher from species to kingdom, the number of common characteristics goes on increasing."
