The ovaries in frog open into cloaca through

Options

A. Bidder's canal
B. Urinogentital duct
C. Single oviduct
D. A pair of oviducts

Answer

To answer the question "The ovaries in frog open into cloaca through," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Female Reproductive System in Frogs**:
- The first step is to understand the anatomy of the female reproductive system in frogs. The ovaries are the organs responsible for producing female gametes (eggs).

2. **Locate the Ovaries**:
- The ovaries are located in the abdominal cavity of the frog. They are paired structures, meaning there are two ovaries.

3. **Understand the Pathway of the Eggs**:
- Once the eggs are produced in the ovaries, they need to travel to the cloaca. The cloaca is a common opening for the digestive, urinary, and reproductive tracts in frogs.

4. **Identify the Connecting Structure**:
- The pathway from the ovaries to the cloaca is through a specific structure. In frogs, this pathway is provided by the oviducts.

5. **Name the Oviducts**:
- The oviducts are also known as fallopian tubes. In frogs, these tubes transport the eggs from the ovaries to the cloaca.

6. **Conclude the Answer**:
- Therefore, the correct answer to the question is that the ovaries in frogs open into the cloaca through the oviducts (fallopian tubes).

### Final Answer:
The ovaries in frogs open into the cloaca through the oviducts (fallopian tubes).
