Step 1: Understanding the Concept:
This question requires matching specific veterinary vaccines with their corresponding formulation type.
Step 2: Detailed Explanation:
Let us analyze the specific details of each vaccine listed:
- Rakshavac-T (A): This is a tissue-culture vaccine used in India to protect cattle against bovine tropical theileriosis. It is formulated as a Live Attenuated Vaccine containing attenuated Theileria annulata schizont-infected lymphoblastoid cell lines. This matches with (III).
- CoxAbic (B): This is a maternal vaccine used in poultry to protect offspring against coccidiosis. It is formulated as a Subunit Vaccine containing purified native affinity-purified antigens from the macrogametes of Eimeria maxima. This matches with (I).
- TICKGARD (C): This is a commercial vaccine designed to control cattle tick infestations (Rhipicephalus microplus). It is formulated as a Recombinant Vaccine containing the recombinant Bm86 gut antigen of the tick. This matches with (IV).
- Anaplaz (D): This is an older, classic vaccine formulation used to protect cattle against bovine anaplasmosis (Anaplasma marginale). It is formulated as a Killed Vaccine. This matches with (II).
Combining these individual linkages, the matching sequence is (A) - (III), (B) - (I), (C) - (IV), (D) - (II).
Step 3: Final Answer:
The matching sequence is represented by option (D).
