select the correct option

Options

A. sea anemone hand clown fish : Mutualism
B. cuckoo and crow: Brood parasitism
C. Ophyrus and bee : Commensalism
D. Sea anemone hermit crab : Parasitism

Answer

To solve the question regarding the correct option for the types of symbiotic relationships, we will analyze each pair mentioned in the video transcript step by step.

### Step 1: Understand the Types of Symbiotic Relationships
Symbiotic relationships can be classified into several types:
- **Mutualism**: Both species benefit from the relationship.
- **Commensalism**: One species benefits while the other is neither helped nor harmed.
- **Parasitism**: One species benefits at the expense of the other.
- **Brood Parasitism**: A specific type of parasitism where one species lays its eggs in the nest of another species.

### Step 2: Analyze Each Option
1. **Anemone and Hand-Clawed Fish**: This is an example of mutualism where both species benefit. The fish gets protection from predators, and the anemone gets food scraps from the fish.

2. **Cuckoo and Crow**: This is an example of brood parasitism. The cuckoo lays its eggs in the crow's nest, and the crow raises the cuckoo's young, often at the expense of its own offspring.

3. **Aphid and Bee**: This is an example of mutualism. Aphids produce honeydew, which bees collect as food. In return, bees help in the pollination of plants where aphids reside.

4. **Anemone and Hermit Crab**: This is an example of commensalism. The hermit crab uses the anemone for protection, while the anemone is not harmed or benefited significantly.

### Step 3: Identify the Correct Answer
Based on the definitions and analysis:
- The correct answer for the relationship that is described as parasitism is **C. anemone and hermit crab**, as it was incorrectly stated in the video. The hermit crab benefits from the anemone, but the anemone does not gain anything significant from this relationship, which aligns more closely with commensalism rather than parasitism.

### Final Answer
The correct option is **C. anemone and hermit crab, commensalism**.
