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, from castor beans, blocks protein creation by disabling ribosomes. Thus, A corresponds to II.

Step 2: Abrin, from Abrus precatorius (rosary pea), is a plant toxin. Historically, it has been noted to have an action like snake venom in forensic toxicology scenarios. Therefore, B matches I.

Step 3: Hyaluronidase, the “spreading factor,” enables toxins/venom to spread through tissues. In veterinary settings, it's used to enhance drug spread in cattle. So, C is equivalent to III. 

Step 4: Histamines are found in bee and wasp venom, producing pain, swelling, and allergic responses. Consequently, D aligns with IV. 

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