Based on classification which set is closer?

Options

A. Silver fish, cuttle fish, jelly-fish
B. Man, chimpanzee, monkey
C. Octopus, oyster, ottor
D. Pigeon, crow, bat

Answer

To determine which set is closer based on classification, we need to analyze the options given in the question. Let's break it down step by step:

### Step 1: Identify the Classification of Each Organism
- **Silverfish**: Belongs to the phylum Arthropoda.
- **Cuttlefish**: Belongs to the phylum Mollusca.
- **Jellyfish**: Belongs to the phylum Cnidaria.
- **Man**: Belongs to the phylum Chordata, class Mammalia.
- **Chimpanzee**: Belongs to the phylum Chordata, class Mammalia.
- **Monkey**: Belongs to the phylum Chordata, class Mammalia.
- **Octopus**: Belongs to the phylum Mollusca.
- **Oyster**: Belongs to the phylum Mollusca.
- **Otter**: Belongs to the phylum Chordata, class Mammalia.
- **Pigeon**: Belongs to the phylum Chordata, class Aves.
- **Crow**: Belongs to the phylum Chordata, class Aves.
- **Bat**: Belongs to the phylum Chordata, class Mammalia.

### Step 2: Group the Options
Now, let's group the organisms based on their classifications:
1. **Option A**: Silverfish, Cuttlefish, Jellyfish
- Different phyla (Arthropoda, Mollusca, Cnidaria).

2. **Option B**: Man, Chimpanzee, Monkey
- All belong to the same phylum (Chordata) and class (Mammalia).

3. **Option C**: Octopus, Oyster, Otter
- Octopus and Oyster are Mollusca, while Otter is Chordata.

4. **Option D**: Pigeon, Crow, Bat
- Pigeon and Crow are Aves, while Bat is Mammalia.

### Step 3: Determine the Closest Set
From the analysis:
- **Option B (Man, Chimpanzee, Monkey)** is the closest set because all three belong to the same family within the class Mammalia. They share a more recent common ancestor compared to the other options.

### Conclusion
The correct answer is **Option B: Man, Chimpanzee, and Monkey**.
