The correct Answer is:
To analyze the given assertion and reason, we will break down the information step by step. ### Step 1: Understanding the Assertion The assertion states that "MLOS are pleomorphic and non-motile monerans." - **MLOS** refers to Mycoplasma-like organisms, which include Mycoplasma and Spiroplasma. - **Pleomorphic** means that these organisms can change their shape. - **Non-motile** indicates that they do not have the ability to move actively, which is consistent with the fact that they lack flagella. ### Step 2: Understanding the Reason The reason states that "They are resistant to antibiotics like penicillin." - **Penicillin** is an antibiotic that targets the cell wall of bacteria by inhibiting the synthesis of peptidoglycan, a key component of bacterial cell walls. - Since Mycoplasma-like organisms do not have a cell wall, they are inherently resistant to penicillin and similar antibiotics. ### Step 3: Evaluating the Truth of the Statements - The assertion is true: MLOS are indeed pleomorphic and non-motile. - The reason is also true: MLOS are resistant to penicillin due to the absence of a cell wall. ### Step 4: Analyzing the Relationship Between Assertion and Reason While both statements are true, the reason does not explain the assertion. The assertion describes the characteristics of MLOS, while the reason discusses their resistance to a specific antibiotic. The resistance is a consequence of their lack of a cell wall, but it does not directly explain why they are pleomorphic or non-motile. ### Conclusion Based on the analysis: - Both the assertion and reason are true. - The reason is not the correct explanation for the assertion. Thus, the correct option is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion. ---
