JEE Main levelOne or more correct optionsDifficulty 2 of 3el157

Select the correct statements.

  1. ACimetidine prevents histamine from binding to receptors in the stomach wall.
  2. BAntihistamines such as brompheniramine reduce the secretion of stomach acid.
  3. CAluminium hydroxide neutralises excess stomach acid.
  4. DTerfenadine is a narcotic analgesic.

Answer: A, C

Cimetidine acts at the stomach receptors and aluminium hydroxide neutralises acid, so statements 1 and 3 are true. Antihistamines like brompheniramine and terfenadine do not affect acid secretion, and terfenadine is an antihistamine, not an analgesic.
