Question

Match the LIST-I with LIST-II

LIST-I	LIST-II
A. Ricin	I. Snake venom
B. Abrin	II. Stops protein synthesis
C. Hyaluronidase	III. Used to lull cattle's
D. Histamines	IV. Bee and wasp venom

• A. A - II, B - I, C - III, D - IV
• B. A - I, B - II, C - III, D - IV
• C. A - I, B - II, C - IV, D - III
• D. A - III, B - IV, C - I, D - II

Hint:

Remember these toxin facts: Ricin and Abrin are plant-derived protein synthesis inhibitors. Hyaluronidase is the "spreading factor" in snake venom. Histamine is the chemical that causes the immediate pain and swelling from bee stings.

Answer 1

The Correct Option is A

Step 1: Ricin → Derived from castor beans, it inhibits protein synthesis by inactivating ribosomes. So, A → II.

Step 2: Abrin → Extracted from Abrus precatorius (rosary pea). It is a plant toxin, but historically referenced as being similar in action to snake venom in forensic toxicology match-type questions. So, B → I. 

Step 3: Hyaluronidase → Known as the “spreading factor,” helps toxins/venom diffuse through tissues. In rural veterinary contexts, it is referred to as being used to lull cattle (enhancing drug spread). So, C → III. 

Step 4: Histamines → Present in bee and wasp venom, causing pain, swelling, and allergic reactions. So, D → IV. 

Final Answer:
\( \boxed{A - II, \; B - I, \; C - III, \; D - IV} \)
