ASSERTION (A): Gram-positive bacteria are generally resistant to complement-mediated lysis. REASON (R): In Gram-positive bacteria, thick peptidoglycan layer prevents insertion of membrane attack complex into the inner membrane.
Directions: In the following question there are two statements, Assertion (A) and Reason (R). Consider both the statements independently and mark your answer as under:
1. If A and R both are correct and R is the correct explanation of A
2. If A and R both are correct and R is not the correct explanation of A
3. If A is correct and R is incorrect
4. If A is incorrect and R is correct
5. If A and R both are incorrect
