- D 1, 2, 3
Answer & Solution
Correct Answer
(C) 2, 4 only
Step-by-step Solution
Detailed explanation
Anti-histamines are drugs which treat symptoms of allergic conditions such as common cold, skin -rashes, conjuctivitis etc. They interfere with natural action of histamine by competing with histamine for binding sites of receptor where histamine exerts its effect. Among the…
