The correct Answer is:
To solve the question "Gill is monopectinate in," we will analyze each option provided in the question step by step. ### Step-by-Step Solution: 1. **Understanding the Term "Monopectinate":** - Monopectinate gills refer to gills that have a single row of gill plates. This structure is important for the classification of certain mollusks. 2. **Analyzing Each Option:** - **Option A: Unio (Commonly known as Mussel)** - Unio has bipectinate gills, meaning it has two rows of gill plates. Therefore, it does not fit the criterion of monopectinate. - **Option B: Chiton** - Chitons possess multipectinate gills, which means they have multiple rows of interlocking gills. This also does not meet the monopectinate classification. - **Option C: Octopus** - Octopuses have feather-like gills, which are not classified as monopectinate. They have a different structure suited for their respiratory needs. - **Option D: Pila (Commonly known as Snail)** - Pila has monopectinate gills, characterized by a single row of gill plates. This matches the definition we are looking for. 3. **Conclusion:** - After analyzing all the options, we find that the correct answer is **D. Pila**, as it is the only organism listed that has monopectinate gills. ### Final Answer: Gill is monopectinate in **Pila (D)**. ---
