The correct Answer is:
To solve the assertion and reason question, we will analyze both statements step by step. ### Step 1: Analyze the Assertion - **Assertion:** "In humans, sex chromosomes determine the sex and various sex-linked characteristics." - **Analysis:** This statement is true. In humans, sex chromosomes (X and Y) play a crucial role in determining an individual's sex (male or female) and also influence certain traits that are linked to these chromosomes. ### Step 2: Analyze the Reason - **Reason:** "In humans, female sex chromosomes are XY while in males, sex chromosomes are XX." - **Analysis:** This statement is false. In humans, females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). Therefore, the reason provided is incorrect. ### Step 3: Conclusion - Since the assertion is true and the reason is false, the correct answer is option **c)**: "If assertion is true but reason is false." ### Final Answer The correct option is **c)**. ---
