• D. (A) $\to$(iv), (B) $\to$(i), (C) $\to$(ii), (D) $\to$(iii)

Answer 1

Answer: (B)

(A) $\to$(ii), (B) $\to$(iii), (C) $\to$(iv), (D) $\to$(i)

• Antibiotics have either cidal (killing) effect or a static (inhibitory) effect on microbes.
  
• Bactericidal antibiotics kill bacteria whereas bacteriostatic antibiotics slow their growth or reproduction.
• The range of bacteria or other microorganisms that are affected by a certain antibiotic is expressed as its spectrum of action.
• Those effective mainly against Gram-positive or Gram-negative bacteria are narrow spectrum antibiotics.
• Receptors are proteins that are crucial to body’s communication process.
• Here, option B matches the appropriate answers and hence is the correct option.
