The correct Answer is:
To solve the question regarding the statements about numerical taxonomy, phylogenetic classification, and cytotaxonomy, we will analyze each statement step by step. ### Step-by-Step Solution: **Step 1: Analyze Statement A** - **Statement A**: "Number and codes are assigned to few of the selected characters in numerical taxonomy." - **Explanation**: Numerical taxonomy, also known as phenetic taxonomy, uses numerical methods to classify organisms based on their observable characteristics. However, the statement is misleading because while numerical taxonomy does involve assigning values to characters, it does not specifically refer to "codes" in a way that is universally recognized. Thus, this statement is **incorrect**. **Step 2: Analyze Statement B** - **Statement B**: "Phylogenetic classification system are based on evolutionary relationships between the various organisms." - **Explanation**: Phylogenetic classification indeed focuses on the evolutionary relationships among organisms, considering their common ancestry and the changes that have occurred over time. This statement is **correct**. **Step 3: Analyze Statement C** - **Statement C**: "Cytotaxonomy is based on cytological information like chromosome number, structure & behaviour." - **Explanation**: Cytotaxonomy is a branch of taxonomy that uses cytological data, such as chromosome number and structure, to classify organisms. This statement is also **correct**. **Step 4: Conclusion** - After analyzing all three statements: - Statement A is incorrect. - Statement B is correct. - Statement C is correct. Thus, the correct option is that only Statement A is incorrect, while Statements B and C are correct. ### Final Answer: - **Correct Option**: Only Statement A is incorrect.

Comprehension In addition to the standar ring systems (such as cyclohexane), cyclic compounds can also be bicylic tricylic, etc. or they can be spirocyclic, bicyclic or bridge head carbons. The point of attachment of two rings are called bridge head atoms. The formal names of bicyclic and related ring system are based on (a) Total number of atoms in the molecule. (b) The number of atoms in each bridge connecting the bridge head atoms. These number are written square bracket in decreasing order. Spirocyclic compounds have two fused rings, but only one bridge head atom. Spirocyclic compounds and named like bicyclic compounds, but have the prefix spirocyclo. Answer the following question : Which of the following is the correct structure of bicyclo [1.1.0] butane?

In the following questions , a statement of assertion (A) is followed by a statement of reason (R). A: Information like chromosome number structure and behaviour is used in cytotaxonomy. R: These become more important when there is no supporting fossil evidence.
