Identify the analogous organs among the following.

Options

A. Edible parts of sweet potato and potato
B. Leaf of cabbage and leaf of Ruscus
C. Mouth parts in cockroach and honey bee
D. Wings of birds and wings of butterfly

Explanation

To identify the analogous organs among the given options, we need to understand what analogous organs are. Analogous organs are structures that perform similar functions but have different evolutionary origins and different anatomical structures. Let's analyze each option step by step.

### Step-by-Step Solution:

1. **Option 1: Edible part of sweet potato and potato**
- The edible parts of sweet potato and potato are both tubers, but they come from different plant families and have different structures. They serve a similar function (storage of nutrients), but they are not considered analogous organs because they are not derived from different evolutionary origins.

2. **Option 2: Leaf of cabbage and leaf of rascals**
- The leaves of cabbage and rascals (presumably referring to a type of plant) are both parts of plants and serve the function of photosynthesis. However, they are similar in structure and evolutionary origin, thus they are not analogous organs.

3. **Option 3: Mouth parts in cockroach and honeybee**
- The mouthparts of cockroaches and honeybees serve the similar function of feeding. However, they are structurally different and come from different evolutionary lineages. Therefore, they are considered analogous organs.

4. **Option 4: Wings of bird and wings of butterfly**
- The wings of birds and butterflies serve the function of flight, but they are structurally different and arise from different evolutionary origins. Hence, they are also considered analogous organs.

### Conclusion:
Among the options provided, the correct answer identifying the analogous organs is:
**C. Mouth parts in cockroach and honeybee**
