  3. CGreen house gas
  4. DAnesthesia

Correct answer

C. Green house gas

Step-by-step solution

Carbon tetrachloride ( CCl₄ ) is a polyhalogen compound that is known to be an ozone-depleting substance and a potent greenhouse gas when released into the atmosphere. The other options correspond to different compounds: Iodoform ( CHI₃ ) is widely used as an antiseptic. Chloroform ( CHCl₃ ) was historically used as a general anesthetic. Antibiotics are antimicrobial drugs and are unrelated to simple halocarbons like CCl₄ . Therefore, among the given options, carbon tetrachloride acts as a greenhouse gas. Answer: G
