Give below are two series A and B
Series A - Maxilla, mandible, labrum, antenna Series B - Blood, bone, tendon, ependyma
Choose the correct option which includes one odd one structure in series A and B
`{:("Series A",,"Series B"),((a)"Maxilla",,"Bone"),((b)"mandible",,"Ependyma"),((c)"Antenna",,"Ependyma"),((d)"Antenna",,"Bone"):}`

Answer

To solve the question, we need to identify the odd one out in both Series A and Series B.

**Step 1: Analyze Series A**
- The structures in Series A are: Maxilla, Mandible, Labrum, Antenna.
- Maxilla, Mandible, and Labrum are all mouthparts of a cockroach, which are involved in feeding.
- Antenna, on the other hand, is a sensory structure and not a mouthpart.

**Conclusion for Series A:** The odd one out is **Antenna**.

**Step 2: Analyze Series B**
- The structures in Series B are: Blood, Bone, Tendon, Ependyma.
- Blood is a fluid connective tissue, while Bone and Tendon are solid connective tissues.
- Ependyma is a type of epithelial tissue that lines the ventricles of the brain and is not a connective tissue.

**Conclusion for Series B:** The odd one out is **Ependyma**.

**Step 3: Identify the correct option**
- The correct option that includes both odd structures (Antenna from Series A and Ependyma from Series B) is option **(c)**.

**Final Answer:** The correct option is **(c) "Antenna", "Ependyma"**.
